When the heart rate temporarily slows down.

Decreased heart rate (HR); usually defined as a heart rate of less than 60 beats per minute.

abnormally slow pulse rate, less than 60 per minute

A slower than normal heart rate – specifically, less than 50 beats per minute.

a very low pulse rate (less than 60 beats per minute).

(noun) heart beat too slow.

(or "Brady") A slower than normal heart rate. In premature babies, usually a heart rate of less than 100 is considered a Brady. Bradycardia often results in apnea.

A hear rate less than 60 beats per minute.

Abnormally low heart rate

a physiological mechanism by which the heart rate is able to be slowed in order to use oxygen most efficiently; used by some animals during times of oxygen depravation such as deep water dives.

is a slower than normal heart rate

A heart rhythm that is slow.

A type of arrhythmia during which the heart beats in a slow rhythm.

a significant drop in the heart rate below the normal rate for that individual. Absolute bradycardia is generally a heartbeat below 90 beats per minute. However, for some babies any significant drop below their normal rate may indicate relative bradycardia, which may be abnormal in certain situations and may have to be treated.

Slowing of the beating of the heart ( 60/min).

A slow heartbeat marked by a pulse rate under 60 beats per minute.

slow heart action, occurring when cetaceans dive.

slowing of heartbeat

Slowness of the heartbeat.

Slowness of the heart rate.

Refers to the ability of some organisms to slow their heart-rate.

abnormally slow heartbeat.

An abnormally slow heart rate.

The condition called bradycardia is a slow heart rate, usually less than 60 beats per minute.

A slow heart rate (less than about 50 beats per minute).

a slow heart rate, usually below 60 beats per minute in adults

Slow heart rate and pulse, usually slower than 60 beats per minute.

a slow heartbeat, typically less than 60 beats per minute (bpm). It may be caused by the sinoatrial (SA) node not working properly or by a condition called heart block.

A slower than normal heartbeat. (Read about " Arrhythmia")

A slower than normal heartbeat, usually less than 60 beats per minute.

A distinctly slow heartbeat, which may be a normal idiosyncrasy or with causes ranging from regular strenuous exercise to abnormally slow heart stimulus to the side-effects of medication. Bradycardia is usually defined as a pulse below sixty beats a minute, or seventy in children.

The momentary slowing of the heart rate in response to a stimulus. Typically, bradycardic responses occur when the individual pays attention. Bradycardic responses are symptomatic of interest (as opposed to boredom or fear).

too low heart beat rate, usually less than 60

Excessively slow heartbeat.

slow heart beat

60 or fewer heartbeats a minute.

An unusually slow heart rate.

An abnormally slow heart rhythm.

Slowed heartbeat.

Low heart rate (usually defined as below 60BPM).

a decrease in the heart rate, below 60bpm for cats and dogs

A condition in which the heart beats at less than 60 beats per minute. This heart rate may be too slow or irregular to meet the body's demands. (This is different than a physically fit person who may have a heart rate below 60.)

Slow heartbeat, usually less than 60 beats per minute.

Low heart rate, usually defined as below 60 bpm in a conscious person.

abnormal slowing of the fetal heart rate.

A slowness of the heart beat.

Excessively slow heart rate. Usually transient and often associated with apnea and desaturation.

Reduction in heart beats/minute.

Slow heartbeat, usually fewer than 100 beats per minute for a baby.

Slow heartbeat. This is a heart rate of less than 60 beats per minute.

Slower than normal heart rate. There are many causes of bradycardia. Sometimes bradycardia is normal and other times it is abnormal and requires treatment.

A slow heart rate, below 50 bpm.

A heartbeat of less than 60 beats per minute.

Heartbeat at abnormally low rate.

This means your baby's heart rate is below 100 beats per minute.

Very slow heart rate.

A heart rate that is slower than normal.

Slow heartbeat. In a normal adult, a heart rate under 60 is considered bradycardic in most circumstances. However, some people have a normal resting pulse lower than this, usually athletes.

A decrease in heart rate. In adults, bradycardia is defined as a HR of less than 60 beats per minute. In the fetus, bradycardia is defined as a baseline HR of less than 120 bpm. Severe fetal bradycardia is anything less than 100 bpm, while moderate fetal bradycardia is a HR of 100-110 and mild fetal bradycardia is a HR between 110-120 bpm.

A slow heart rate, usually defined as less than 60 beats per minute.

A heart rate, usually less than 60 bpm.

When the Heart Rate (HR) is slow ( 60 beats per minute)

Slowing of the heart rate below the age specified rate for 5 seconds or greater

Bradycardia is defined as a heart rate of under 60 beats per minute, though it is seldom symptomatic until the rate drops below 50 beat/min. It is also less commonly known as brachycardia.

A slow heartbeat characterized by a pulse rate of below 60 beats per minute

A heart rhythm with a rate below 60 beats per minute in a human adult.

Bradycardia, as applied in adult medicine, is defined as a resting heart rate of under 60 beats per minute, though it is seldom symptomatic until the rate drops below 50 beat/min. http://www.emedicine.com/emerg/topic534.htm Sinus Bradycardia eMedicine Trained athletes tend to have slow resting heart rates, and resting bradycardia in athletes should not be considered abnormal if the individual has no symptoms associated with it.
