What are the symptoms of cardiac arrest?

Cardiac arrest is a medical term given to the sudden loss of heart function. The most common symptoms of cardiac arrest include sudden collapse and loss of consciousness. This is usually followed by a loss of pulse and stopping of breathing. In most cases, cardiac rest occurs suddenly and without warning. In some cases, the patient may experience symptoms such as chest pain or dizziness before collapsing.

Most patients who experience cardiac arrest have no warning signs, so if warning signs occur, emergency medical care should be sought immediately. The most commonly reported symptoms of cardiac arrest include chest pain, dizziness, and shortness of breath. Some patients may faint or partially lose consciousness.

Sudden fatigue, muscle weakness, or vomiting are also potential symptoms of cardiac arrest. Heart palpitations or the development of a rapid heartbeat may be present, with or without chest pain. In cases where there are symptoms of cardiac arrest, collapse usually occurs soon after symptoms develop.

Urgent medical attention is required whenever symptoms of cardiac arrest are suspected. Death can occur within minutes of collapse if proper medical treatment is not obtained. Once in the hospital, any supportive care deemed necessary is provided until the patient is stable enough to undergo medical tests. This supportive care may include oxygen therapy or connection to a machine that regulates the patient's heartbeat.

Medical tests are often done when a patient is experiencing possible symptoms of cardiac arrest. Blood tests can determine if cardiac enzymes in the blood are abnormal and can help detect other heart-related problems. An electrocardiogram, or ECG, is often used to monitor the electrical activity of the heart. Other tests, such as X-rays or an ultrasound of the heart, may also be considered necessary.

A patient who has experienced symptoms of cardiac arrest is usually monitored in a hospital for a few days to make sure the medical crisis is over and the patient's health is stable. Caregivers are often taught the correct way to perform CPR in case symptoms return. Prescription medications or surgical intervention may be necessary, depending on the underlying cause of the cardiac crisis. The patient may be advised to get a portable defibrillator, a small machine designed to send electrical shocks to the heart if the heart stops. Any questions or concerns about possible symptoms of cardiac arrest should be discussed with a doctor or other medical professional.
