Supraventricular Tachycardias

Supraventricular tachycardias (SVTs) comprise a group of usually benign arrhythmias that originate from cardiac tissue at or above the His bundle. SVTs include inappropriate sinus tachycardia, atrial tachycardias (ATs), atrial flutter (AFL), junctional tachycardia, atrioventricular nodal reentrant tachycardia (AVNRT), and forms of accessory pathway–mediated reentrant tachycardias (atrioventricular reentrant tachycardia [AVRT]). Although mostly benign, symptoms can be debilitating, in the form of palpitations, shortness of breath, chest discomfort, dizziness, and/or syncope; rarely, SVTs can result in cardiomyopathy due to incessant arrhythmia. This review covers the epidemiology, diagnosis, management, and classification of SVTs.  This review contains 14 figures, 17 tables, and 61 references.

Premature Beats

Supraventricular arrhythmias encompass atrial premature beats, supraventricular tachycardias (SVTs), and atrial fibrillation. SVT is used to describe tachycardias in which the mechanism involves tissue from the His bundle or above, thus including atrial tachycardias, atrioventricular nodal reentrant tachycardia, and atrioventricular reentrant tachycardia due to accessory pathways. Atrial fibrillation is not included among the SVTs and is described elsewhere. The term tachycardia refers to atrial and/or ventricular rates greater than 100 beats per minute at rest. Atrial premature beats, the most common supraventricular arrhythmia, can be seen in Holter recordings in the majority of healthy individuals, and increase in frequency with age and presence of structural heart disease. Paroxysmal SVTs that can be terminated by vagal manoeuvres are usually reentrant tachycardias involving the atrioventricular node, such as atrioventricular nodal reentrant tachycardia or atrioventricular reentrant tachycardia. Symptoms may result in a poor quality of life. Rarely, patients with the Wolff–Parkinson–White syndrome develop atrial fibrillation that may degenerate into ventricular fibrillation in case the anterograde refractory period of the accessory pathway is very short and permanent forms of SVTs result in tachycardiomyopathy with left ventricular dysfunction. Paroxysmal SVT can be terminated by vagal manoeuvres, adenosine, overdrive pacing, and DC cardioversion. Atrial flutter, the most common atrial tachycardia, is a macro-reentrant atrial tachycardia that can be terminated by drugs, overdrive atrial pacing, and DC cardioversion. Most SVTs can be successfully treated by catheter ablation facilitated by modern electroanatomical mapping systems. Long-term antiarrhythmic drug therapy may be required for patients who are not suitable for or cured by catheter ablation.

Antiarrhythmic Medications

Supraventricular tachycardias (SVTs) comprise a group of arrhythmias for which the atria and/or atrioventricular (AV) node are integral to sustaining the rhythm. These arrhythmias typically have a benign natural history but account for a considerable proportion of patients presenting with symptoms including palpitations, shortness of breath, chest discomfort, dizziness, and, on occasion, syncope. They affect a broad range of patients, from young, otherwise healthy adults and children to elderly patients with multiple comorbidities. Although medical management with AV nodal blocking medications or antiarrhythmic medications is a reasonable first-line approach, catheter ablation is a definitive, most often curable option that has minimal risk and offers the chance of avoiding long-term medications. This chapter covers the epidemiology, diagnosis, and management of SVTs, which include atrioventricular nodal reentrant tachycardia (AVNRT), atrioventricular reentrant tachycardia (AVRT), atrial tachycardia (AT), and others (atrial flutter, inappropriate sinus tachycardia, and junctional tachycardia). Atrial fibrillation, which is more prevalent than all other SVTs combined, are discussed elsewhere. Figures describe the differential diagnosis of tachycardia with narrow and wide QRS complexes, the relationship between the response to intravenous adenosine and the cause of tachycardia, the mechanism of tachycardia induction in patients with dual AV node conduction pathways, and the management of atrial flutter. Electrocardiograms illustrate features of various forms of SVT. This review contains 11 highly rendered figures (included 6 twelve-lead ECGs), 1 table, and 69 references.

Anxiety Levels

Objective: Electrophysiological study (EPS) has been widely used in the diagnosis and treatment of tachycardia. The objective of this study was to determine the anxiety levels in children before EPS procedure. Method: Patients (n=45) who were hospitalized for EPS between March and September of 2019 were included n this cross-sectional study, The patient group consisting of children aged 8-18 years old was compared with age- and sex- matched controls (n=46). We evaluated the severity of anxiety at the time of assessment using the Screen for Child Anxiety Related Emotional Disorders (SCARED) scale. The forms were filled out by both children and their parents. Results: The mean age of the patients in the study group consisting of 23 girls and 22 boys was 13.91±2.84 years. Diagnoses of cases treated due to arrhythmia were as follows: atrioventricular reentrant tachycardia (44.4%), atrioventricular nodal reentrant tachycardia (31%), ventricular tachycardia (11.2%), sinus tachycardia (8.8%), and atrial flutter (4.4%). Anxiety levels were higher in children who were hospitalized for EPS procedure compared to the control group (p<0.001). Conclusion: As far as we know, our study is the first in Turkey to measure the level of anxiety in children undergoing cardiac EPS due to tachycardia. Electrophysiological study procedure increases anxiety in children. Further studies in which methods to reduce anxiety are needed are studied.

Atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT) are two common arrhythmias with high similarity. Automatic electrocardiogram (ECG) detection using machine learning and neural networks has replaced manual detection, but few studies distinguishing AVNRT from AVRT have been reported. This study proposed a classification algorithm using bottleneck attention module (BAM)-based deep residual network (ResNet) through two-lead ECG records. Specifically, ResNet possessed sufficient network depth to extract abundant features, and BAM was introduced to optimize weight assignment of feature maps by fusing together channel and spatial information. Seven types of ECG signals from four public databases were used to pretrain the proposed classification model, which was then fine-tuned using the experimental dataset. The AVNRT and AVRT detection precisions were 98.95% and 87.47%, sensitivities were 87.52% and 98.58%, and the [Formula: see text]1-scores were 92.82% and 92.68%, respectively. These findings showed that our proposed classification model achieved excellent inter-patient classification performance and can assist doctors in the diagnosis of AVNRT and AVRT.
