EKG Q & A

What is an EKG?

An EKG is a test that looks for problems with the electrical activity in the heart. This test depicts electrical activity as line tracings that the doctor can evaluate. Abnormalities in those tracings may indicate specific problems with the heart.

When are EKGs necessary?

The Doctors may recommend an EKG for several reasons, including:

  • Finding the cause of unexplained chest pain or other symptoms.
  • Ruling out or confirming a heart attack.
  • Evaluating the safety and/or effectiveness of medications that affect the heart.
  • Evaluating the function of mechanical devices implanted in the heart.
  • Evaluating the heart’s general function.

What should I expect during an EKG?

During an EKG, you’ll be asked to expose your chest. The Doctor. or another member of the staff will attach several electrodes to your chest to measure your heart’s activity. These electrodes are connected to a machine that produces line tracings based on the measured electrical activity.

You should lie still during the test and may need to hold your breath temporarily. Most EKGs are complete within 10 minutes or less.

What do the results mean?

The results of the EKG may be normal or abnormal. A normal EKG means that the line tracings followed an expected pattern; test results are abnormal if the line tracings didn’t follow a normal pattern. An abnormal test may indicate that the heart was beating too slowly, too quickly, or irregularly.

If the EKG is abnormal, The Doctor will usually order further testing to investigate the issue. If the EKG is normal, further testing may or may not be needed.

What are the risks of an EKG?

EKGs are noninvasive and unlikely to cause any side effects or complications. However, in some cases, an EKG may be normal even when a problem is present. For this reason, The doctor will usually order more tests for a patient who has a normal EKG in spite of worrisome symptoms.

Electrocardiography (ECG or EKG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin. These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle’s electrophysiologic pattern of depolarizing and repolarizing during each heartbeat. It is a very commonly performed cardiology test.

The overall goal of performing electrocardiography is to obtain information about the structure and function of the heart. Medical uses for this information are varied and generally relate to having a need for knowledge of the structure and/or function.

For patients with symptoms of a heart problem, an electrocardiogram, or EKG, is an important test

Annual exams are an important part of preventive care for patients of all ages. The doctors of Health Associates offer annual exams, school physicals, and work physicals to patients in Pembroke Pines, Florida, and the surrounding area. Patients interested in this service can contact the Health Associates, to schedule an appointment.

Some indications for performing electrocardiography include:

  • Perioperative monitoring in which any form of anesthesia is involved (e.g. monitored anesthesia care, general anesthesia); typically both intraoperative and postoperative
  • As a part of a pre-operative assessment some time before a surgical procedure (especially for those with known cardiovascular disease or who are undergoing invasive or cardiac, vascular or pulmonary procedures, or who will receive general anesthesia)
  • Cardiac stress testing
  • Computed tomography angiography (CTA) and Magnetic resonance angiography (MRA) of the heart (ECG is used to “gate” the scanning so that the anatomical position of the heart is steady)
  • Biotelemetry of patients for any of the above reasons and such monitoring can include internal and external defibrillators and pacemakers.
  • Suspected myocardial infarction (heart attack) or new chest pain
  • Suspected pulmonary embolism or new shortness of breath
  • A third heart sound, fourth heart sound, a cardiac murmur, or other findings to suggest structural heart disease
  • Perceived cardiac dysrhythmias, either by pulse or palpitations
  • Monitoring of known cardiac dysrhythmias
  • Fainting or collapse
  • Seizures
  • Monitoring the effects of a heart medication (e.g. drug-induced QT prolongation)
  • Assessing severity of electrolyte abnormalities, such as hyperkalemia
  • Hypertrophic cardiomyopathy screening in adolescents as part of a sports physical out of concern for sudden cardiac death (varies by country)
