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 correct diagnosis is sinus rhythm with premature ventricular contractions and ventricular parasystole (Figure 2). Figure 2. Courtesy of Philip J. Podrid, MD. The rhythm is irregular. There are ...

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 ...

The regular arrhythmia occurring at the beginning of the electrocardiogram was identified as ventricular bigeminy. Single ventricular premature complexes (VPCs), as well as pairs and triplets of VPCs, ...

DEAR DR. ROACH: What’s the difference between atrial fibrillation and premature ventricular contractions, aka PVCs (extra heartbeats)? -- M. ANSWER: Both AFib and PVCs are rhythm disturbances of the ...

It is well known that QRS complexes originating from the ventricle such as premature ventricular contractions, or QRS complexes during an accelerated ventricular rhythm, ventricular tachycardia, or ...

Remember that T wave inversions and ST segment depression are normal in leads V1 to V3 in the presence of a right bundle branch block; thus, myocardial ischemia technically cannot be easily determined ...

An electrocardiogram (Fig. 1) of the Case Records of the Massachusetts General Hospital (in the September 18 issue) needs a few comments or corrections. First of all, the entire tracing in Figure 1 is ...

Purpose: Infantile Pompe disease is caused by deficiency of lysosomal acid α-glucosidase. Trials with recombinant human acid α-glucosidase enzyme replacement therapy (ERT) show a decrease in left ...
