Cardiology – HADCng

An electrocardiogram (ECG or EKG) is a test that checks how your heart is functioning by measuring the electrical activity of the heart. With each heart beat, an electrical impulse travels through your heart. This impulse causes the muscle to squeeze and pump blood from the heart.

An ECG measures and records the electrical activity that passes through the heart. A Cardiologist can determine if this electrical activity is normal or irregular.

An ECG may be recommended if you are experiencing arrhythmia, chest pain, or palpitations and an abnormal ECG result can be a signal of a number of different heart conditions.

Why is it done?

To detect abnormal heart rhythms that may have caused blood clots to form.
Detect heart problems, including a recent or ongoing heart attack, abnormal heart rhythms, coronary artery blockage, areas of damaged heart muscle (from a prior heart attack), enlargement of the heart, and inflammation of the sac surrounding the heart (pericarditis).
Detect non-heart conditions such as electrolyte imbalances and lung diseases. Monitor recovery from a heart attack, progression of heart disease, or the effectiveness of certain heart medications or a pacemaker.
Rule out hidden heart disease in patients about to undergo surgery.
Monitor recovery from a heart attack, progression of heart disease, or the effectiveness of certain heart medications or a pacemaker.

How do you prepare?

You do not have to restrict what you eat or drink before your ECG, although it is recommended that you not smoke just before the test. You will be asked to remove your jewelry and wear a hospital gown and if you are the hairy type you might be required to shave some of the hair around the chest region.
