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 ...
If a premature atrial contraction occurs when the AV node has not yer recovered from the refractory period, the PAC will fail to conduct to the ventricles and there will not be a QRS complex ...
Most of us have had that unsettling sensation when our heart seems to flutter or "skip" a beat — but when heart palpitations start happening more frequently, you may wonder if it’s something to get ...
Patients requiring a pacemaker often have atrial fibrillation (AF), which increases the risk of thromboembolism and, consequently, the risk of morbidity and mortality. To maintain sinus rhythms, ...
Data from large-scale epidemiologic studies to support an association between PM exposure and atrial arrhythmias are lacking. The findings of the aforementioned studies are limited in generalizability ...
Note the premature ventricular contraction (PVC) that triggers the AVNRT in this ECG. If a premature atrial contraction (PAC) or premature ventricular contraction (PVC) occurs at the right time, the ...
Our heartbeat serves as a vital indicator, which shows how well our heart functions. The heart experiences irregular rhythms when it beats either too quickly, too slowly or irregularly. Arrhythmias ...
