lifestyle
2

Advanced cardiac electrophysiology evaluation

Detailed heart rhythm assessment including Holter monitoring and possible electrophysiology study to evaluate significance of QRS abnormalities and risk for arrhythmias.

monitoring
3

Antiarrhythmic therapy when indicated

Pharmacological management with rhythm or rate-control medications when QRS abnormalities indicate risk for ventricular arrhythmias or conduction disturbances. Requires ongoing ECG monitoring.

medication

Additional treatment options

Implantable cardioverter-defibrillator (ICD) consideration

Device therapy for high-risk patients with QRS abnormalities indicating vulnerability to life-threatening ventricular arrhythmias. Decision based on ejection fraction and risk stratification.

procedure

Arrhythmia trigger avoidance

Identification and avoidance of personal arrhythmia triggers such as excessive caffeine, stimulant medications, and extreme physical exertion. Includes electrolyte maintenance through hydration.

lifestyle

Electrolyte-balancing nutrition

Dietary approach ensuring adequate potassium, magnesium, and other electrolytes that support normal cardiac conduction. Includes foods like leafy greens, bananas, and lean proteins.
