An elderly woman is admitted with atrial fibrillation and fast ventricular rate. She is then treated with 5 mg IV metoprolol. She becomes obtunded.
Changes in heart rate caused by activity, diet, medications, and age are normal and common. Abnormally slow heart rates are usually those below 60 beats a minute and can be either harmless or life threatening. At certain times, though, such as during sleep, heart rate will be slow and still be normal.
Elderly people, for example, are more prone to bradycardia. In general, for adults, a resting heart rate of fewer than 60 beats per minute BPM qualifies as bradycardia. But there are exceptions.
Jump to content. Having bradycardia say "bray-dee-KAR-dee-uh" means that your heart beats very slowly. For most people, a heart rate of 60 to beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, it is slower than normal.
Bradycardia is a condition typically defined wherein an individual has a resting heart rate of under 60 beats per minute BPM in adults. When symptomatic, it may cause fatigue, weakness, dizziness, sweating, and at very low rates, fainting. Highly trained athletes may also have athletic heart syndromea very slow resting heart rate that occurs as a sport adaptation and helps prevent tachycardia during training.

Bradycardia is a type of abnormal heart rhythm, or arrhythmia. It occurs when the heart beats very slowly — less than 60 beats per minute. A normal heartbeat begins with an electrical impulse from the sinus nodea small area in the heart's right atrium right upper chamber.
Bradycardia is an abnormally slow heart rate of less than 60 beats per minute. A normal heartbeat is between 60 and beats per minute. Here's what happens during a normal heartbeat: The electrical signal that starts a heartbeat comes from the heart's sinus node, the natural pacemaker located in the upper portion of the right atrium.
The Bradycardia Algorithm lists the proper sequence used to treat a patient demonstrating symptomatic bradycardia with a pulse. Bradycardia is typically associated with a slow heartbeat heart rate of less than 60 beats per minute. Although some people, particularly well-trained athletes, may have a resting heart rate of beats per minute without any symptoms, it is important to understand and be able to identify the difference between symptomatic and asymptomatic bradycardia.
