Premature ventricular complexes (PVCs) are extra heartbeats originating from the heart’s lower chambers, potentially causing palpitations or fluttering sensations. While occasional PVCs are common, ...
This case highlights the diagnostic value of Holter ECG monitoring in uncovering spontaneous arrhythmia mechanisms. Several ...
The diagnosis is sinus rhythm, with acute inferior wall ST-segment elevation myocardial infarction (STEMI), ventricular triplet (nonsustained monomorphic VT), premature ventricular complex, R-on-T ...
Background: The availability of stored intracardiac electrograms from implantable defibrillators (ICDs) has facilitated the study of the mechanisms of ventricular tachyarrhythmia onset. This study ...
At times it can be difficult to distinguish "SVT with aberrancy" from ventricular tachycardia. This QRS morphology has a typical left bundle branch block pattern, is irregular and does not meet the ...
In the last few weeks, the Skeptical Cardiologist has had a run on with patients with premature atrial contractions (PACs). I've discussed in detail premature ventricular contractions (PVCs) here and ...
The ECG shows sinus rhythm at 100 to 110 beats per minute with an isolated (conducted) premature atrial contraction and a ventricular couplet. The QRS duration is about 0.15 sec and the frontal plane ...
As more companies turn an eye to at-home ECG measurements, AliveCor received clearance from the Food and Drug Administration for its newest suite of algorithms. The Mountain View, Calif.-based startup ...
