The heart's pacemaker is the sinoatrial (SA) node, a group of cells located in the right atrium that generates electrical impulses to regulate heartbeats. Factors that can cause the SA node to change its rate include physical activity, stress, hormonal changes (such as adrenaline release), and autonomic nervous system influences (sympathetic or parasympathetic stimulation). Additionally, conditions like fever, electrolyte imbalances, and certain medications can also affect the pacemaker's activity.
What else can I help you with?
What causes the pacemaker to change the rate at which the heart beats?
The sympatetic nerve increases the SA node to speed up the heart rate The parasympathetic nerve uses the vagus nerve which decreases HR
What causes the heart's pacemaker to change the rate at which the heart beats?
Nerves The sympatetic nerve increases the SA node to speed up the heart rate The parasympathetic nerve uses the vagus nerve which decreases HR
Are the purjinke fibers the hearts pacemaker?
SA node (sinoatrial) is primary pacemaker, SV node (sinoventricular) is secondary. Purkinje fibers are the very last pacemaker on the list. If a heart gets down to firing on that it, the person is just about dead and needs IMMEDIATE medical attention. Its max rate per minute is 30. A normal heart rate is b/n 60-100 beats per minute.

What does artificial pacemaker do?
An Artificial Pacemaker basically regulates the rate of the heart beat depending on the needs of the body.
What are the group of cells that adjusts the heart rate?
Pacemaker
What is the success rate of a pacemaker?
Approximately 99% successful.
What name is the rate set by the heart pacemaker?
Pacemakers are set by the surgeon-physician at the time it is implanted. Most times, the pacemaker is simply set to a normal heart rate (around 70-80 beats per minute). The primary function of the pacemaker is to restore a more regular beat when the heart cannot maintain a normal heart rate. You should consult your physician-surgeon for particulars about your pacemaker, its use, function, and signs/symptoms to watch for after the pacemaker is implanted.
Why do you need a pacemaker if you already had bypass?
A bypass merely clears the flow in the arteries, the pacemaker keep the heart beating at a steady rate.
Is a pacemaker a group of cells located in the left atrium?
A pacemaker is a device inserted into the heart to regulate the heart beats or heart rate
What is the function of your natural pacemaker?
The contraction of heart (cardiac) muscle in all animals with hearts is initiated by chemical impulses. The rate at which these impulses fire controls the heart rate. The cells that create these rhythmical impulses are called pacemaker cells, and they directly control the heart rate.
A pacemaker adjusts the heart rate to correspond to the body's?
Oxygen needs
What property makes the normal pacemaker region of the heart function as a pacemaker?
The property of the normal pacemaker region is able to provide a normal setting for the heart to beat. It allows the heart to beat at a regular rate.
