An Electrocardiogram (EKG) is an important diagnostic tool for cardiologists. With this technology, small electrodes are attacked to the patient’s body. These electrodes detect tiny electrical changes on the skin as the heart muscle sends out a signal. Normally, the heartbeat has a regular rhythm. The strength and variation of the electrical signals can be used to diagnose disorders of the heart and the vascular (circulatory) system (blood flowing through the heart and the body).

With a 12-lead EKG, 12 different electrical signals are recorded at approximately the same time. The signals are then analyzed for information on any or all of the following: the heart rate, rhythm of the heartbeats, the condition of the heart’s chambers, possible damage to the heart, the effects of a given drug on the heart, and the effects of a pacemaker.

The 12-lead EKG test is performed in our Miami clinic. Electrodes attached to sticky pads (about the size of a silver dollar) will be placed on the chest, arms and legs. These  electrodes are connected to the EKG recording machine. The EKG recorders register electrical signals produced by each heart beat, which are then recorded and printed for Dr. Diego.

If Dr. Diego orders an EKG, the patient may participate in all of his or her normal daily activities before the appointment. He or she is allowed to eat, drink, and take the same medications as usual on the day of the EKG.

Patients are asked not to use body moisturizer or lotion before an EKG. Men with chest hair may need to be shaved in a small area.

There is no electric shock for the patient having an EKG. The procedure takes only a few minutes and is painless.

A 12-Lead EKG Will Help Dr. Diego Diagnose:

  • Chest pain
  • Heart arrhythmia
  • Heart murmur
  • Function of the heart in patients with high blood pressure.
