Rhythm disorders can be irregularity in the rhythm or change in the heart rate (increase or decrease). Commonest irregularity in the heart rhythm is due to abnormal beats originating from the lower chambers known as&nbsp;<em><span style=\"color: #008000;\">ventricular ectopic beats<\/span> (<span style=\"color: #008000;\">VPB or VPC &#8211; ventricular premature complexes<\/span>)<\/em>. Increase in heart rate can be due to physiological causes like exercise or due to simple disease states like fever. A decrease in heart rate can occur during deep sleep and when the body temperature falls below normal (<em><span style=\"color: #000000;\">hypothermia<\/span>)<\/em>. There are several disease states which can reduce heart rate like a decrease in the function of the thyroid gland (hypothyroidism) and <span style=\"color: #008000;\"><em>complete heart block<\/em><\/span>. In complete heart block, the signals generate by the natural pacemaker of the heart, namely sinoatrial node, does not get conducted down to the lower chambers of the heart.

The device used to record the ECG is known as the&nbsp;<span style=\"color: #008000;\"><em><a href=\"\/general\/electrocardiograph\/\">electrocardiograph<\/a><\/em><\/span>.

Continuous ECG monitoring for evaluation of cardiac arrhythmia is now commonplace in intensive care units and operating rooms.<\/p>\n<p>Apart from recording of the electrical activity from the body surface as discussed, above, it is also possible to record electrical signals from within the heart using electrodes introduced into the heart chambers through the blood vessels.
