An ECG is therefore an essential part of the investigation of any patient with a slow pulse rate, and indeed of any patient with dizziness, syncope or breathlessness. The causes of sinus bradycardia have been discussed in Chapter 1 (see Box 1.2, p. 5). Escape rhythms have been discussed in Chapter 2 (p. 82).
Full Answer
Using small sensors (electrodes) attached to your chest and arms, it records electrical signals as they travel through your heart. Because an ECG can't record bradycardia unless it happens during the test, your doctor might have you use a portable ECG device at home. These devices include: Holter monitor.
Patients are seldom aware that their heart rate is slow, but they can certainly be aware of the effects of a bradycardia.

When Don’t You Need an EKG? Typically you don’t need an EKG if you don’t have any heart disease risk factors or you’re not experiencing any symptoms of heart problems. The test isn’t useful in regular checkups for individuals with no heart disease risk factors like high blood pressure or heart disease symptoms like chest pain.
Initial treatment of any patient with bradycardia should focus on support of airway and breathing (Box 2). Provide supplementary oxygen, place the patient on a monitor, evaluate blood pressure and oxyhemoglobin saturation, and establish intravenous (IV) access. Obtain an ECG to better define the rhythm.
An ECG can show if the heart is beating too slow, too fast or not at all. Because an ECG can't detect bradycardia unless the slow heartbeat occurs during the test, your health care provider might recommend a portable ECG device.

If you have bradycardia, your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart rate is very slow and the heart can't pump enough oxygen-rich blood to the body. If this happens, you may feel dizzy, very tired or weak, and short of breath.
Bradycardia can sometimes be diagnosed in your physician's office with an electrocardiogram (ECG or EKG). But when bradycardia is an occasional event, a regular ECG may be normal. If this is the case, your doctor may give you an ECG monitor to wear at home that will record your heart rhythm over time.

The initial interventions within the bradycardia algorithm for all infants and children with symptomatic bradycardia include the following: Identify and treat the underlying cause. Provide oxygen. Attach a cardiac monitor for rhythm identification.
A bradycardia may be the primary cause of low cardiac output. Hypothyroidism, hypothermia, drugs such as beta blockers and calcium channels blockers, inferior myocardial ischemia and conduction system dysfunction may all cause significant bradycardia.
Adults and children who have a low pulse and experience symptoms such as chest pain, fainting, or exercise intolerance should also go to the hospital. A person should contact a doctor about bradycardia when they: experience an unexplained change in heart rate that lasts for several days.
Symptomatic bradycardia, heart rate typically <50 beats per minute with presence of symptoms, is identified and treated directed at the underlying cause. Maintain a patent airway with assisted breathing as necessary. Administer supplemental oxygen if hypoxic.
There are two main types of bradyarrhythmia: sinus node dysfunction and atrioventricular (AV) blocks.
Bradycardia means your heart rate is slow. This can be completely normal and desirable, but sometimes it can be an abnormal heart rhythm (arrhythmia). If you have bradycardia and you have certain symptoms along with the slow heart rate, then it means your heartbeat is too slow.
You may not have any symptoms of bradycardia. But if you do have a slow heart rate and any of these symptoms, call your doctor:
Your doctor will feel your pulse to get your heart rate and will use tests to get more information about your heart rate and rhythm. A simple EKG can show the rhythm that is causing the slow heart rate, but you may need to wear an ambulatory monitor. The monitor is used to keep track of your heart rate and rhythm over a longer period of time.
If you have bradycardia but do not have any symptoms, or if the bradycardia doesn’t happen often or last long, you may not need treatment. Sometimes bradycardia is a good thing and is the goal of treatment.
Bradycardia (brad-e-KAHR-dee-uh) is a slower than normal heart rate. The hearts of adults at rest usually beat between 60 and 100 times a minute. If you have bradycardia, your heart beats fewer than 60 times a minute.
A slower than normal heartbeat (bradycardia) can prevent the brain and other organs from getting enough oxygen, possibly causing these signs and symptoms:
In a typical 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 into the ventricles, causing them to contract and pump blood.
Bradycardia is often associated with damage to heart tissue from some type of heart disease. Anything that increases the risk of heart problems can increase the risk of bradycardia. Risk factors for heart disease include:
Bradycardia can be caused by certain medications, particularly if they are taken at high doses, so it's important to take all medications as directed. Although bradycardia is not typically preventable, health care providers recommend strategies to reduce the risk of developing heart disease. Take the following heart-healthy steps:
A slow ventricular rate can accompany atrial flutter or atrial fibrillation because of slow conduction through the AV node and His bundle systems ( Figs 4.9 and 4.10 ). This may be the result of treatment with drugs that delay AV nodal conduction, such as digoxin, beta- blockers or verapamil, but can occur because of conducting tissue disease.
Symptoms are not caused by first degree block, second degree block of the Wenckebach or Mobitz type 2 varieties, left anterior hemiblock or the bundle branch blocks.
