EKG Testing

Setting The Standard For EKG Testing

The electrical activity of your heart is measured by a test called an electrocardiogram (EKG or ECG). An EKG can show if your heart is working properly. 

An electrocardiogram is one of the most basic and quickest tests for evaluating the heart. On the chest, arms, and legs, electrodes are positioned in well-considered positions. The electrodes and an EKG testing machine are connected by lead wires.

The heart's electrical activity is then recorded, analyzed, and printed.

An EKG records the electrical impulses to reveal the heart's rate of beats. The report will include the regularity or irregularity of the beat. It also states the strength and timing of the electrical impulses as they pass through the various heart chambers. Changes in an ECG or EKG can indicate a variety of heart conditions.

EKG machines are used in hospitals, clinics, and doctor's offices. They are also portable so that somebody can use them in other settings, such as a patient's home.

Why Would I Need an Electrocardiogram?

Your doctor may order an electrocardiogram (EKG) for a variety of reasons, including:

  • To determine the source of chest pain
  • Assess heart-related issues such as fainting, dizziness, shortness of breath, and extreme tiredness.
  • Detecting irregular heartbeats
  • To aid in determining the heart's overall health prior to procedures such as surgery.  Or used as a follow-up medical check for conditions such as a heart attack or following cardiac catheterization or heart surgery.
  • Allows examinations of how a pacemaker implant works.
  • To assess the efficacy of certain heart medications
  • Often, a baseline is obtained, which is done during a routine checkup. Medical professionals can use this information to compare what is happening at the moment of issues.

EKG Testing FAQ's

Arrhythmia: issues with the heart’s pace or rhythm

Heart attacks: a sudden blockage of blood flow to the heart that can damage or destroy part of the heart muscle

Enlargement of the heart: due to high blood pressure, a valve problem, or other conditions

Abnormal myocardial ischemia: reduced blood flow to the heart muscle

Cardiac arrest: the sudden cessation of heartbeat.

An EKG is usually done as part of a routine physical exam.  However, medical professionals can use them to check for symptoms like chest pain or shortness of breath. If you have a history of heart disease, you may need an EKG more often.

  • You’ve experienced unexplained dizziness, fainting, or palpitations.
  • You’ve been diagnosed with or suspected of having heart failure or coronary artery disease (CAD).
  • You’re being treated for high blood pressure (hypertension), an irregular heartbeat, or other heart condition.
  • You’re a smoker.
  • You have diabetes.
  • There is a history of early heart disease in your family.
  • You take certain medications that can affect the electrical activity of your heart.
  • You’ve had a recent viral infection, such as the flu.

A healthcare provider performs an EKG, usually a nurse, doctor, or other medical personnel trained in performing the test.

It takes around 10 minutes to complete an EKG, and is painless. You will take the exam while lying on your back on a testing table. Your arms, legs, and chest will all have electrodes attached by the technician. Wires connect the electrodes to the EKG device.

You will be required to remain still for the duration of the test. Furthermore, short-term breath-holding exercises may be required of you. The test is not painful, but you may feel a slight prick when the electrodes are attached.

After the test, the electrodes will be removed, and you can return to your normal activities.

  • Obesity
  • Pregnancy
  • Abdominal fluid accumulation
  • Anatomical considerations such as chest size and the location of the heart within the chest.
  • Movement during the examination
  • It would help if you either exercised or quit smoking before the test.
  • Certain medications
  • Electrolyte imbalances in the blood, such as too much or too little potassium, magnesium, or calcium.

You do not need to do anything special to prepare for an EKG. However, you should wear loose-fitting clothing to the test so that the electrodes can be attached easily.

You may want to avoid caffeine or nicotine for a few hours before the test. Caffeine and nicotine can interfere with the results of the test.
