The S-A node
arrythmyia
Arrhythmia is a problem with the rate or rhythm of the heartbeat of a person.
Poetic foot is the basic unit of measuring rhythm in poetry.
The basic pace of the heart is set by the sinoatrial (SA) node, often referred to as the heart's natural pacemaker. The SA node generates electrical impulses that initiate each heartbeat, causing the heart muscles to contract and pump blood. This intrinsic rhythm is influenced by various factors, including autonomic nervous system inputs and hormones, which can adjust the heart rate according to the body's needs.
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.
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.
Atrial fibrillation or A-fib. I know this one from experience.
Rhythm
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.
The basic rhythm of breathing is controlled by part of the brain called the Medulla.
Sinus rhythm refers to the normal heartbeat rhythm generated by the sinoatrial (SA) node, the heart's natural pacemaker. It is characterized by a regular rhythm with a heart rate typically ranging from 60 to 100 beats per minute, and each heartbeat is preceded by a P wave on an electrocardiogram (ECG). This rhythm indicates that the electrical impulses are originating from the SA node, ensuring efficient and coordinated contractions of the heart. Maintaining sinus rhythm is crucial for effective blood circulation and overall heart health.
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.
