What is the name of the cell that starts the heartbeat?
A special group of cells begin the signal to start your heartbeat. These cells are in the sinoatrial (SA) node. Normally, the SA node fires the signal at about 60 to 100 times per minute at rest. In sinus bradycardia, the node fires less than 60 times per minute. Bradycardia means a slow heartbeat.

Why is my heart rate slow?
When the sinus node is producing these electrical impulses at a relatively reduced rate, the heart rate becomes slow and sinus bradycardia is said to be present. Causes of sinus bradycardia can be either transient or persistent. Persistent causes are more likely to require treatment.
What is the purpose of ECG for bradycardia?
First, the doctor needs to examine an electrocardiogram (ECG) while the bradycardia is present to determine whether it is due to sinus bradycardia or heart block. Then, the doctor must determine whether the bradycardia is likely to be persistent or due to a transient cause, such as an infection.
What is the ventricle of the heart called when it can't get information from the sinus node?
When the ventricles of the heart can't get information from the sinus node about how fast to beat, they use information from another special part of the heart between the atria and ventricles called the AV node . This results in a potentially dangerous bradycardia. 7.
What nerve is responsible for sinus bradycardia?
Transient sinus bradycardia is most often caused by the increased tone in the vagus nerve, such as during sleep. This nerve helps regulate the control of the heart, lungs, and digestive tract.

Side effects of drugs (notably beta blockers, digitalis, verapamil, diltiazem, amiodarone, klonidin) – These drugs affect the pacemaker cells in the sinoatrial node.
What is the treatment for bradycardia?
Permanent symptomatic bradycardias are treated with artificial pacemakers. Note that patients with chronotropic incompetence may require pacemaker to increase exercise capacity and reduce symptoms. Patients with tachy-brady syndrome may also necessitate rate controlling drugs (e.g beta-blockers) and anticoagulation (if atrial fibrillation or flutter can be verified).

Is sinus bradycardia normal?
Sinus bradycardia (SB) is considered a normal finding in the following circumstances: During sleep. Well-trained individuals display SB at rest due to high vagal tone. These individuals have developed a highly efficient left ventricle, capable of generating sufficient cardiac output at low heart rates.
What is the normal heart rate for bradycardia?
While some consider bradycardia to be a heart rate <60 bpm, this is in dispute and most consider rates of <50 bpm to represent bradycardia.

What is the name of the cell that sends out electrical signals?
Normal heartbeat. In a normal heart rhythm, a tiny cluster of cells at the sinus node sends out an electrical signal. The signal then travels through the atria to the atrioventricular (AV) node and then passes into the ventricles, causing them to contract and pump out blood. Bradycardia. Open pop-up dialog box.
Why is my heart slow?
Bradycardia, shown on the right, is a slower heart rhythm that may occur because the sinus node in the heart may be discharging electrical impulses at a slower than normal rate.
