Senator John Fetterman, 56, the Democratic Senator from Pennsylvania was hospitalized on November 13, 2025, after he fell down during an early morning walk near his home in Braddock Pennsylvania. The news was confirmed by his office, stating that the fall was triggered by a ventricular fibrillation flare-up.

According to a leading media outlet, Fetterman said, "If you thought my face looked bad before, wait until you see it now." Fetterman's office reportedly reassured the public that his recent injury was minor and that he was doing well.

He had to be admitted to the hospital for a precautionary measure to ensure his physical condition was closely monitored. Apart from his current health status, the democratic senator from Pennsylvania previously suffered a stroke in 2022.

What is ventricular fibrillation?

Ventricular fibrillation or VF is an extremely dangerous heart rhythm that can lead to sudden cardiac death. According to the American Heart Association (AHA) abnormal heart rhythm can be fatal within minutes. The heart association claims that disordered electrical activity allows your heart's lower chamber to quiver instead of beating normally. This activity blocks your heart from pumping blood, resulting in collapse and cardiac arrest.

The National Institute of Health (NIH) states, "VF is often linked to underlying structural heart disease. Three percent to 12% of cases of myocardial infarction (MI) develop VF during the acute phase."

Causes of ventricular fibrillation

Healthcare professionals warned that ventricular fibrillation or VF can be triggered by several reasons, including:

  • Insufficient blood flow to the heart muscle
  • Damaged heart muscle due to a heart attack
  • Cardiomyopathy, which is a disease of the heart muscle
  • Drug toxicity
  • Electrocution accident
  • Heart attack
  • Congenital heart disease
  • Heart surgery
  • Extreme high or low potassium levels
  • Problems with arota
  • Severe body infection
  • Sudden cardiac arrest

Signs of cardiac arrest

The AHA says that ventricular fibrillation can cause sudden cardiac arrest which may require immediate medical attention. Some of the common signs of cardiac arrest include.

  • Loss of consciousness.
  • Gasping for breath
  • Sudden collapse
  • No pulse

How to reduce risk for ventricular fibrillation

"Primary prevention has been a significant factor in reducing VF-related SCDs. Most VF transition from VT and other VA and hence identifying such arrhythmias at an early stage can help prevent VF," the National Institute of Health (NIH) explains. "In patients with symptoms suspected to be related to VA, detection using ambulatory electrocardiography and implanted cardiac monitors is recommended. Healthcare professionals should offer family members of patients with inherited arrhythmia syndromes genetic testing and counseling for risk stratification."

In most cases, to reduce the risk of ventricular fibrillation, the American Heart Association (AHA) say that healthcare professionals may recommend certain medications to control heart rhythm problems. You may also have to implant a surgical device called an implantable cardioverter defibrillator (ICD), which allows to detect and correct your abnormal heart rates by sending shock to your heart.
