Background.Computerized electrocardiogram (ECG) analysis has been of tremendous help for noncardiologists, but can we rely on it? The importance of ST depression and T wave inversions in lead aVL has not been emphasized and not well recognized across all specialties.Objective.This study’s goal was to analyze if there is a discrepancy of interpretation by physicians from different specialties and a computer-generated ECG reading in regard to a TWI in lead aVL.Methods.In this multidisciplinary prospective study, a single ECG with isolated TWI in lead aVL that was interpreted by the computer as normal was given to all participants to interpret in writing. The readings by all physicians were compared by level of education and by specialty to one another and to the computer interpretation.Results.A total of 191 physicians participated in the study. Of the 191 physicians 48 (25.1%) identified and 143 (74.9%) did not identify the isolated TWI in lead aVL.Conclusion.Our study demonstrated that 74.9% did not recognize the abnormality. New and subtle ECG findings should be emphasized in their training so as not to miss significant findings that could cause morbidity and mortality.

Unnecessary Intervention

Introduction: Although rare, iatrogenic cases of pneumopericardium have been documented following laparoscopic surgery and mechanical ventilation. Electrocardiogram (ECG) changes, including ST-segment depressions and T-wave inversions, have been documented in cases of pneumopericardium, and can mimic more concerning causes of chest pain including myocardial ischemia or pulmonary embolism. Case Report: This unique case describes a patient who presented with chest pain and ST-segment changes on ECG hours after a laparoscopic inguinal hernia repair and who was found to have pneumopericardium. Conclusion: While iatrogenic pneumopericardium is often self-limiting and rarely requires intervention, it is critical to differentiate pneumopericardium from other etiologies of chest pain, including myocardial ischemia and pulmonary embolism, to prevent unnecessary intervention.

Wrong Interpretation

Electrocardiogram (ECG) is one of the most important and time-tested tool for appropriate interpretation and diagnosis of coronary artery disease (CAD) and other structural & electrical cardiac abnormalities. Erroneous misplacement of surface ECG-leads (lead reversal) may result in wrong interpretation as well as unnecessary investigations, admission to hospital and improper treatment. Early & prompt recognition of lead-reversal is imperative to avoid inappropriate & harmful therapeutic interventions to the patients. This casereport focuses on an interesting scenario of ECG-lead misplacement, which will aid in detection, exclusion and further prevention of ECG lead misplacement.Bangladesh Heart Journal 2016; 31(2) : 104-108

Abstract Introduction Sotalol (SOT) is a Class 3 antiarrhythmic drug and commonly used for various arrhythmia treatments. However; it can prolong QT interval and lead to malignant arrhythmias. Empagliflozin is a selective SGLT-2 inhibitor used in the treatment of Type 2 diabetes and has been shown to have positive effects on cardiovascular outcomes. Since the effect of empagliflozin (EMPA) on potassium channel activation is not yet known, there is no recommendation for the concomitant use of these drugs. Purpose In this study, we aimed to evaluate possible protective effects of empagliflozin in sotalol induced QT prolongation. Materials and methods Twenty-four male Wistar Alba rats were randomized into four groups. The first (control) group (n: 6) received only serum physiologic (1ml) via orogastric gavage (OG). The second (EMPA) group (n: 6) received EMPA (10 mg/kg) via OG. The third (SOT) group (n: 6) received SOT (80 mg/kg) via OG. The fourth (EMPA+SOT) group (n: 6) received EMPA (10 mg/kg) and SOT (80 mg/kg) via OG. Under anesthesia; PR, QT intervals and heart rate (HR) were measured and QTc value was also calculated at second hour on lead II using electrocardiogram (ECG). Results In the SOT group; QT intervals, T wave durations and QTc values were found to be statistically longer than the control group, whereas HR was found to be lower than the control group (p<0.01). In the EMPA+SOT group; QT intervals, T wave durations and QTc values were significantly lower and HR was significantly higher compared to the SOT group (p<0.001, p<0.01, p<0.001, p<0.001 respectively) (Table) Conclusion In the present study, we detected that EMPA significantly ameliorates SOT induced QT prolongation. In addition to this, we have also shown that EMPA can be used safely with SOT in clinical practice. With more clinical trials, the routine use of EMPA may be suggested to prevent QTc prolongation in diabetic patients receiving SOT. Finally; our study indicates that EMPA can effect on potassium channels. Funding Acknowledgement Type of funding source: None

A man was found dead in a room where two dogs and a cat were wandering freely. His legs were bare and his underpants presented a few small tears. The deceased exhibited a partial emasculation but with only a small amount of bleeding. No other significant injuries were found, particularly no defence lesions. Death was natural, caused by the rupture of a myocardial infarct. A small piece of connective tissue was found in the gastric contents of one of the dogs. This fragment, as well as bloodstained hairs from its jaws, were analysed for DNA.

Abstract Ureaplasma species are small, fastidious bacteria that frequently colonize the lower reproductive tract of asymptomatic hosts. These organisms have been well described to cause chorioamnionitis, neonatal infection, and urethritis, and to a lesser degree surgical site infection and infection in transplant recipients. Outside of these settings, invasive Ureaplasma infections are rare. We describe the case of a young woman receiving rituximab for multiple sclerosis who presented with fever and bilateral renal abscesses due to Ureaplasma spp., which was successfully treated with oral doxycycline. We searched the literature for cases of invasive Ureaplasma infection and found a patient population that predominates with humoral immunodeficiency, either congenital or iatrogenic. Diagnostic and therapeutic interventions are discussed.

Abstract: The veterinary cardiology has growing importance in equine medicine. There are studies of standardization of electrocardiographic parameters of many races, according to their stature and ability. However, no studies are in the literature with the American Miniature Horse. To evaluate the electrocardiogram (ECG) tracing configuration of this breed at rest and to verify the influence of age and sex on ECG parameters, 203 horses including 143 females and 60 males were divided into four age groups (foals, yearlings, adults and elderly). Electrocardiographic parameters were performed by computerized electrocardiogram (TEB), and the parameters were evaluated in six leads of frontal plane (Lead I, II, III, aVR, aVL and aVF) and base-apex (BA). Heart rates (HR) decreased with increasing age were higher in males than in females. Sinus tachycardia followed by sinus arrhythmia was dominant in both sexes. The cardiac axis was higher in males and ranged between 120° and 150° for foals, 30° and 60° for yearlings and adults, and 60° and 90° for the elderly. The P wave was bifid in several animals. The P-wave amplitude and T-wave duration from lead II and BA were larger in males than in females. The majority of the animals exhibited ST segment depression and a negative T-wave. The most common QRS complex morphology was Qr. Differences were observed between the electrocardiographic tracings of males and females, and age influenced the ECG parameters. Therefore, this study established the ECG patterns for the American Miniature Horse breed and could be used to determine the influence of age and sex on several of the studied variables.

This article is to design and develop a programming electrocardiogram (ECG) generator. It can be used to test the efficiency of algorithms and to calibration and maintenance of electrocardiograph equipment. We simplified and modified the three coupled ordinary differential equations of McSharry’s model to single differential equation to generate the synthetic ECG waveforms. This generator can provide the adjusted amplitude, heart rate, QRS-complex slopes, and P- and T-wave position parameters. The system can set the rage of the average gear rate from 20 to 120 beat per minute (BPM) with an adjustable variation of 1 BPM. The parameters of the adjusted synthetic ECG model can be stored in Flash memory of the system through Universal Serial Bus (USB) 2.0 interface. The results were generated four different ECG waveforms for test which are Lead I, Lead II, hyperkalaemia and left bundle branch block. According to the experimental results, the system can not only generate the ECG waveforms of the setting heart rate but also can adjust the different types of ECG waveforms. ECG generator will generate the synthetic electrocardiograms for testing the electrocardiogram analytic algorithms. ECG generator will generate the synthetic electrocardiograms for testing the electrocardiogram analytic algorithms.
