We arrives on a side street two blocks away where there is a stretch of brick houses with high stoops and iron fences. View in context The firing died down and soldiers, talking eagerly, streamed out of a side street.
An irregular heartbeat is an arrhythmia (also called dysrhythmia). Heart rates can also be irregular. A normal heart rate is 50 to 100 beats per minute. Arrhythmias and abnormal heart rates don't necessarily occur together. Arrhythmias can occur with a normal heart rate, or with heart rates that are slow (called bradyarrhythmias -- less than 50 beats per minute).
Bradycardia, also known as bradyarrhythmia, is a slow heart rate, namely, a resting heart rate of under 60 beats per minute (BPM) in adults.It is a type of cardiac arrhythmia. ventricular bradycardia, also known as ventricular escape rhythm or idioventricular rhythm, is a heart rate of less than 50 bpm. This is a safety mechanism when there is lack of electrical impulse or stimuli from the atrium.
