Ablation Arrhythmia Bradycardia 
HeartRhythm
DECEMBER 31, 2024
Notwithstanding many insightful observations, the electrocardiogram (ECG) arguably ignited the big bang in our understanding of cardiac arrhythmias. Using ECG recording and deductive reasoning, our teachers and predecessors classified the bradycardias and tachycardias and proposed many mechanisms, subsequently proven to be correct.

However, he suddenly developed a series of malignant ventricular arrhythmias. Below are printouts of some of the arrhythmias recorded. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. The arrhythmia starts with a PVC having a short coupling interval.

Introduction The incidence of arrhythmia in heart failure with non-reduced ejection fraction (HFnon-rEF) in patients who have a history of hospitalisation is unclear. Methods and analysis This is a multicentre single arm study to evaluate the usefulness of ILR for detecting arrhythmia.

Ventricular tachycardia is a potentially life threatening cardiac arrhythmia. Chronic recurrent monomorphic VT like fascicular tachycardia and right ventricular outflow tract tachycardia are also amenable to electrophysiological mapping and ablation. If the rate is very fast, hemodynamic deterioration can occur rapidly.

Ablation to prevent recurrent flutter was performed. On the contrary — much ( if not most ) of the time, we begin arrhythmia treatment of a WCT before we know with 100% certainty what the rhythm is. It emphasizes a series of KEY concepts in emergency arrhythmia diagnosis and management.

3] So a patient with WPW can have the pattern induced by ischemia, and there is also a report of a patient with pre-existing WPW which was “ablated” by myocardial infarction after an LAD occlusion.[4] Delta waves are seen in 11/12 leads. In most of these leads — the PR interval is clearly shortened, with resultant QRS widening.

The possibility of an ischemic cause of the ventricular arrhythmia has to be considered! Below in Figure-5 is a 10-minute continuous lead II recording on oral Flecainide, now showing sinus bradycardia without a single PVC! A workup was undertaken in search of a cause of the patient's ventricular arrhythmia. No PVCs are seen.
