The crescent-shaped pacemaker of the heart that initiates depolarization under normal conditions is the?
Sinoatrial node
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.
The p wave of a normal electrocardiogram indicates?
Atrial Depolarization.
Is artificial pacemaker useful?
Yes. They allow people with some types of heart conditions to lead normal lives, wher they might otherwise be dead or sickly.
Normal cardiac rhythm is determined by what?
The sinoatrial node is the pacemaker of the heart and determines the normal rhythm.Sinoatrial Node
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.
Is the pacemaker of the heart under normal circumstances is called the sinoatrial SA node?
Yes the sinoatrial node is also called the pacemaker under all circumstances
How many pacemakers can a person have?
A person can only have one pacemaker. A pacemaker helps if you have problems with the beating of your heart. If you have two pacemakers the beating of your heart won't be normal.
What device assists the heart to maintain a normal rthythm?
A device that assists the heart to maintain a normal rhythm is called a pacemaker.
What device assists the heart to maintain a normal rhythm?
The device that assists the heart to maintain a normal rhythm is called a pacemaker.
What is the Role of artificial pacemaker in heart if patient has a heart disease?
Pacemaker help to normalize the electrical impulses conductance of the heart. usually people with pacemaker has an abnormal impulse originated from their SA node. so, the pacemaker is placed so that the heart can contract at a normal rate and thus prevent arrhythmia.
What device would be used to regulate a heartbeat?
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.
