Conventional dual-chamber pacing maintains atrioventricular synchrony but results in high percentages of ventricular pacing, which causes ventricular desynchronization and has been linked to an ...
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 ...
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 ...
Atrial fibrillation (AFib) is a disorder centered in the heart's upper chambers that causes the organ to be unable to maintain its regular rhythm. The condition can cause palpitations, fatigue, ...
Extended cardiac monitoring in patients and the use of implantable cardiovascular electronic devices can increase detection of atrial fibrillation (AF), but the devices have limitations including ...
Palpitations due to premature beats, either ventricular contractions (PVCs) or atrial contractions (PACs), can be extremely vexing even when we know they are benign. For many individuals, these ...
