Ventricular Flutter

Ventricular flutter causes 

Ventricular flutter is typically caused by: 

• Heart disease: such as coronary artery disease or previous heart attacks. 
• Electrolyte imbalances: like low potassium or magnesium levels. 
• Structural damage to the heart: including scar tissue from past heart conditions. 
• Certain medications or drugs that disrupt the heart's electrical impulses. 

Ventricular flutter risk factors 

Several factors increase the risk of developing ventricular flutter, including: 

• A history of heart disease or prior heart attacks. 
• Previous arrhythmias or abnormal heart rhythms. 
• High blood pressure or a sedentary lifestyle. 
• Family history of heart disease or arrhythmias. 
• Smoking, excessive alcohol use, or drug abuse. 

Ventricular flutter symptoms 

The symptoms of ventricular flutter can include: 

• Dizziness, lightheadedness, or fainting. 
• Chest pain or discomfort. 
• Shortness of breath or rapid breathing. 
• Palpitations or irregular heartbeat. 
• In severe cases, sudden cardiac arrest, requiring emergency care. 

Ventricular flutter diagnosis 

To diagnose ventricular flutter, doctors use: 

• An electrocardiogram (ECG or EKG) to detect abnormal electrical activity in the heart. 
• Additional tests, such as blood tests or imaging, to identify underlying heart conditions. 
• A Holter monitor or stress test to detect irregularities over a longer period. 

Ventricular flutter treatment 

Treatment options for ventricular flutter include: 

• Immediate defibrillation (shock therapy) to restore normal heart rhythm. 
• Antiarrhythmic medications to control and stabilize the heart rhythm. 
• Implantable cardioverter-defibrillator (ICD) for long-term prevention in high-risk patients. 
• Addressing underlying heart conditions with medications, lifestyle changes, or surgery. 

When to Seek Care 

You should seek medical care immediately if you experience symptoms like chest pain, dizziness, fainting or shortness of breath. If you feel like there’s a chance you’re experiencing a heart attack, call 9-1-1 or go to an emergency room right away.  

If you are experiencing new or unusual irregular heartbeats, especially if you have a history of heart disease or arrhythmias.
