According to the CDC, a person dies every thirty-six seconds from cardiovascular disease. Electrocardiography, also known as ECG, is a common medical procedure for physicians to monitor the electrical signals that pass through the heart. An ECG allows physicians to quickly identify and diagnose potential cardiac abnormalities or injury. Sudden cardiac arrest and arrival to the emergency department can create fear, anxiety, and uncertainty. Early diagnosis and identification of cardiac abnormalities can be life-saving.2 For patients, a better understanding of medical practices can ease the unknown and foster a better foundation for discussion with physicians.
