A new study has linked prolonged P-wave duration to increased risk for sudden cardiac death (SCD), independent of cardiovascular risk factors and atrial fibrillation. 1 This suggests P-wave ...

The atrial rate during atrial tachycardia is usually between 100 and 200 beats per minute. A narrow complex tachycardia results with P wave morphologies ... to decreased cardiac output and ...

Atrial fibrillation is the most common chronic arrhythmia. It is characterized by erratic atrial electrical activity with atrial rates of 400 to 600 beats per minute. The P wave is absent on the ...
