Heartbeat is termed "intrinsic" because it originates from the heart's own pacemaker cells, specifically the sinoatrial (SA) node, which generates electrical impulses independently of external stimuli. This intrinsic ability allows the heart to maintain a regular rhythm and pace regardless of external factors, ensuring consistent blood circulation. The autonomic nervous system can modulate this intrinsic rhythm, but it is fundamentally self-regulated.
Semiconductor in pure form (i.e. without doping) is called intrinsic or i-type semiconductor. The no of charge carrier in this case is determined by the materials itself only and not by the impurities. In an intrinsic semiconductor number of excited free electron is equal to the number of holes.
Intrinsic factor is glycoprotein that is produced by the parietal cells of the stomach.
Extrinsic
at higher values of temperature the intrinsic carrier concentration become comparable to or greater than doping concentration in extrinsic semiconductors. thus majority and minority carrier concentration increases with increase in temperature and it behaves like intrinsic semiconductor.
An intransic material is a material that have been used in doping process.There are two type of intrinsic material n type and p type.
Arrhythmia
It is called Systole.

The sinoatrial (SA) node has the fastest intrinsic rate in the cardiac conduction system, typically firing at a rate of 60-100 beats per minute in a healthy heart. It serves as the primary pacemaker of the heart, initiating each heartbeat by generating electrical impulses.

There are several nerves that regulate the heartbeat. The heartbeat starts when a signal is given off from the SA node. The main nerves in the heart are called the Purkinje Fibers.
It is called a Irregular heartbeat.
The relaxation phase of the heartbeat is called diastole. During diastole, the heart ventricles relax and fill with blood in preparation for the next contraction.
