Why the study?
Do ventricular arrhythmias on 24-hour ambulatory ECG monitoring predict cardiac death in patients with left ventricular dysfunction and heart failure?
Do ventricular arrhythmias on 24-hour ambulatory ECG monitoring predict cardiac death in patients with left ventricular dysfunction and heart failure?
Longer and faster ventricular tachycardia on 24-hour ambulatory ECG monitoring identifies patients with left ventricular dysfunction and heart failure at increased risk of sudden cardiac death.
No takes yet. Share an insight, caveat, or question.
Low LVEF with VT on 24h ECG identifies higher-risk HF patients; hypothesis-generating for arrhythmia-guided risk stratification pending prospective trials.
