Act Fast During Cardiac Arrest
February 10, 2020
We continue our February heart health series as we discuss cardiac arrest. Over 300,000 cardiac arrest episodes occur annually, and without immediate action, they can become deadly.
Cardiac Arrest vs. Heart Attacks
These terms are mistakenly used interchangeably but are different. Heart attacks result from a blockage that inhibits blood flow to your heart. Cardiac arrest occurs when your heart stops beating caused by a malfunction in its electrical system. Blood can’t pump to vital organs like the brain and lungs once the heart stops beating. This condition can happen with or without symptoms.What Causes Cardiac Arrest?
Almost any heart condition can cause cardiac arrest.- Heart attacks: Heart attacks create scarring in heart tissue, which can lead to arrhythmias, an irregular heartbeat. Cardiac arrest can occur during the first few months after a heart attack.
- Electrical irregularities: The electrical system in your heart contracts the muscle creating the beat. Any electrical anomalies put you at risk for arrhythmias and cardiac arrest.
- High blood pressure: Problems with blood pressure can thicken the walls of your heart, leading to an ineffective heartbeat.
- Heart medications: Certain heart meds can create arrhythmias and cardiac arrest. Blood level changes in potassium and magnesium pose risks as well.
- Drug use: Recreational drugs can bring on cardiac arrest even in a healthy individual.
Watch For Symptoms
Spotting symptoms of cardiac arrest can mean the difference between life and death, so awareness is key. Symptoms include:- Loss of consciousness
- No breathing or gasping for air
- Sudden unresponsiveness to stimuli like nudging or speaking loudly
- Lack of blinking, speech, or movement
