An abnormality in the rhythm of the heart beat is called arrhythmia. The cause of this can be little or nothing or can be very serious.
arrythmyia
Arrhythmia is a problem with the rate or rhythm of the heartbeat of a person.
The S-A node
sinoatrial
A compensatory pause on an ECG refers to a pause in heart rhythm that follows a premature beat or extra heartbeat. This pause allows the heart to reset and resume its normal rhythm. It is a normal mechanism of the heart's electrical system to ensure effective pumping.
A skipped beat is a beat that is not in rhythm (the 2-second rhythm) whereas an accelerated heartbeat is that heartbeat that happens before the 2 seconds interval elapses, and both are a risk to the normal operation of the heart.
Hemostasis refers to the process that prevents and stops bleeding, maintaining blood in a fluid state within the vascular system. Dysrhythmia is an abnormality in the rhythm of the heartbeat, which can lead to irregular heartbeats, affecting the heart's ability to pump effectively. Palpitation is the sensation of feeling one's own heartbeat, which may feel rapid, fluttering, or pounding, often associated with anxiety, stress, or underlying heart conditions.
Atrial fibrillation or A-fib. I know this one from experience.
It is the variance in time between each heartbeat. ECG, and blood pressure tests are often used to measure the variance in the rhythm of the heart.
Rhythm has to do with patterns of sound, in terms of their stress or duration. Pitch and tone are not relevant to rhythm. The simplest rhythm is the sound of a heartbeat: da-DUM-da-DUM-da-DUM. Here the "DUM" is louder (stress) and twice as long (duration) than the "da". This is called iambic rhythm in poetry or triple time in music. Ask someone not musically challenged, they will show you, or get a good laugh trying.
A pacemaker is a device that is commonly used to regulate an irregular heartbeat by sending electrical impulses to the heart to help it maintain a normal rhythm.
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.
