What is it?
Core pathophysiology of Ventricular Fibrillation.
Commonly affected: Affected cardiovascular structure
How it develops
- TriggerTriggering factor for Ventricular Fibrillation
- Cardiovascular changeSpecific changes in cardiovascular structure
- ManifestationCharacteristic clinical features appear
- CourseCourse and complications depend on treatment
Symptoms
- Characteristic cardiovascular symptomClassic Ventricular Fibrillation presentation
- Palpitations or dyspneaVaries by condition
- Reduced exercise toleranceReduced cardiovascular function
How it is examined
- Cardiac auscultation/inspectionMurmurs, gallops, JVP
- ECG/echocardiogramKey diagnostic studies
Imaging
CXR assesses cardiomegaly/pulmonary status.
- CXR findings
Echocardiogram or cardiac MRI for further assessment.
- Echo findings
Non-surgical care
- Medical therapyEvidence-based medication
- Risk factor managementControl BP, lipids, DM
- Lifestyle modificationDiet, exercise, smoking cessation
Conservative options are generally tried first. Medications listed here can have side effects — discuss them with your prescriber.
When surgery is considered
Failed medical therapy or progressive/high-risk
Procedures that may be discussed
- Interventional procedure (PCI, ablation, etc.)
- Cardiac surgery
Outlook
Good with appropriate therapy; complication prevention is key.
