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.

Ventricular Tachycardias

Few studies have investigated patients with pulmonary hypertension and arrhythmias. Data on electrophysiological studies in these patients are rare. In a retrospective dual-centre design, we analysed data from patients with indications for electrophysiological study. Fifty-five patients with pulmonary hypertension were included (Dana Point Classification: group 1: 14, group 2: 23, group 3: 4, group 4: 8, group 5: 2, and 4 patients with exercised-induced pulmonary hypertension). Clinical data, 6-minute walk distance, laboratory values, and echocardiography were collected/performed. Nonsustained ventricular tachycardia was the most frequent indication (n=15) for an electrophysiological study, followed by atrial flutter (n=14). In summary 36 ablations were performed and 25 of them were successful (atrial flutter 12 of 14 and atrioventricular nodal reentrant tachycardia 4 of 4). Fluoroscopy time was 16±14.4 minutes. Electrophysiological studies in patients with pulmonary hypertension are feasible and safe. Ablation procedures are as effective in these patients as in non-PAH patients with atrial flutter and atrioventricular nodal reentrant tachycardia and should be performed likewise. The prognostic relevance of ventricular stimulations and inducible ventricular tachycardias in these patients is still unclear and requires further investigation.

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.

Atrioventricular Reentrant Tachycardia

Abstract Background Supraventricular arrhythmias represent a diagnostic challenge. Its prevalence and causes are not well established, given the impossibility to differentiate between all different types of supraventricular tachycardias (SVT). There are several supraventricular arrhythmias, but we focus on: 1) Atrial tachycardia (AT) 2) Junctional tachycardia (JT) 3) Atrial fibrillation (AF) 4) Atrial flutter (AA) 5) Atrioventricular nodal reentrant tachycardia (AVNRT), and 6) Atrioventricular reentrant tachycardia (AVRT). The electrocardiographic diagnosis is based on the presence of P-waves, its morphology and relationship with the QRS complex, and the relationship between the atrial and ventricular frequency. Purpose The purpose of this study was to create a helpful clinical tool that could serve the physician as a guide to determine a diagnosis and initial treatment. Additionally, we wanted to establish the sensitivity and specificity of the algorithm. Methods It is a diagnostic test study. We include 190 electrocardiograms of different SVT of patients undergoing electrophysiological studies. The data consists of 760 observations from two different readings of the electrocardiograms. Results 104 of 112 AF, were correctly identified using the algorithm, with a sensitivity and specificity of 92.9% and 99.1%, respectively (95% CI: 0.86–0.96). 76 of 760 were AA, and 62 were correctly diagnosed, with a sensitivity and specificity of 81.6% and 95.5%, respectively (95% CI 0.71–0.88). 50 of the 72 AT were correctly classified, with a sensitivity of 69.4% and specificity of 97.4% (95% CI 0.58–0.78). 99 of 152 AVNRT were identified with a sensitivity and specificity of 64.5% and 87%, respectively (95% CI 0.84–0.89). 254 of 344 AVRT were diagnosed correctly with a sensitivity of 73.8% and specificity of 88.2% (95% CI 0.68–0.78). Finally, 1 of 4 JT were identified, with a sensitivity and specificity of 25% and 99.1% respectively (95% CI 0.04–0.69). Conclusion The algorithm is an excellent diagnostic tool to identify atrial flutter, atrial fibrillation and atrioventricular reentrant tachycardia.
