A fascinating electrophysiology case. What is this wide complex tachycardia, and how best to manage it?

Dr. Smith's ECG Blog

She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. Answer : The ECG above shows a regular wide complex tachycardia. Said differently, the ECG shows a rather slow ventricular tachycardia with a 2:1 VA conduction. Cardiac output (CO) was being maintained by the tachycardia.

Ablation of Ventricular Tachycardia from Right Ventricular Aneurysms in Patients with Arrhythmogenic Cardiomyopathy Guided by Intracardiac Echocardiography

HeartRhythm

The best approach for ablating ventricular tachycardia (VT) targeting right ventricular free wall (RVFW) aneurysms in arrhythmogenic right ventricular cardiomyopathy (ARVC) remains undefined.

Acute Dyspnea and Right Bundle Branch Block

Dr. Smith's ECG Blog

LV aneurysm has QS-waves, so this couldn't be LV aneurysm, right? RBBB makes it mandatory that there are R'-waves even in the presence of LV aneurysm. Additionally, it is very difficult to differentiate subacute reperfused OMI from LV aneurysm: both have Q-waves and inverted T-waves. This is HIGHLY suspicious for OMI.

A Giant Left Atrial Appendage Aneurysm With Incessant Atrial Tachycardia

Journal of Cardiovascular Electrophysiology

ABSTRACT Introduction Left atrial appendage aneurysm (LAAA) is a rare congenital cardiac anomaly that involves the progressive dilatation of the left atrial appendage (LAA), predisposing the patient to serious complications such as atrial tachyarrhythmias, life-threatening systemic thromboembolism, and cardiac dysfunction.

Tachycardia must make you doubt an ACS or STEMI diagnosis; put it all in clinical context

Dr. Smith's ECG Blog

He was rushed by residents into our critical care room with a diagnosis of STEMI, and they handed me this ECG: There is sinus tachycardia with ST elevation in II, III, and aVF, as well as V4-V6. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock. He had this ECG recorded. Are the lungs clear?

Chest discomfort, Sinus Tachycardia, Q-waves, ST Elevation, and Intermittent Wide Complex Tachycardia. Activate the Cath Lab?

Dr. Smith's ECG Blog

His previous echo one month prior shows the same thing: “consistent with old infarct in LAD vascular territory, with EF 45%” "I think there is something else causing his tachycardia which is exaggerating his EKG findings and mimicking an acute myocardial infarction." The patient spontaneously converted back to sinus tachycardia.

Pulsed field ablation of atrial tachyarrhythmia originating from atrial aeptal aneurysm

HeartRhythm

4 We hereby reported a case of atrial tachycardia (AT)/AF originating from an aneurysmal interatrial septum (AIS) that was successfully mapped with a high-density mapping catheter and eliminated with pulsed field ablation (PFA). Extra-pulmonary vein (PV) triggers have been reported in up to 4.9-15%
