Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Chest discomfort
Pain, pressure, tightness, or squeezing sensation in the chest that may radiate to the arm, jaw, or back.
Seek immediate emergency care if chest pain is severe, crushing, or accompanied by shortness of breath, sweating, or nausea.
Shortness of breath
Difficulty breathing or feeling breathless, especially during physical activity or at rest.
Seek immediate care if shortness of breath is sudden, severe, or occurs at rest with chest pain or dizziness.
Fainting
Sudden loss of consciousness, often brief, that may be preceded by dizziness or weakness.
Seek immediate emergency care for any fainting episode, as it may indicate a serious heart condition.
Heart palpitations
(cardiovascular)Awareness of rapid, fluttering, pounding, or irregular heartbeat.
Frequency: 50-70% of patients
Dizziness
(neurologic)Feeling lightheaded, unsteady, or faint, which may occur when standing up or throughout the day.
Frequency: 30-50% of patients
Fatigue
(constitutional)Persistent tiredness, lack of energy, or feeling exhausted even after adequate rest.
Frequency: 40-60% of patients
Nausea
(gastrointestinal)Feeling sick to the stomach with an urge to vomit, which may accompany other cardiac symptoms.
Frequency: 15-25% of patients
Rapid heartbeat
(cardiovascular)Heart rate faster than normal (tachycardia), often felt as pounding in the chest.
Frequency: 35-55% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Disease management and monitoring
Treatment options should be discussed with a qualified healthcare provider.
Continuous cardiac monitoring
Extended heart rhythm monitoring via Holter monitor or event recorder to characterize arrhythmia patterns and guide treatment decisions.
Antiarrhythmic medication therapy
Cardiac medications to control heart rate, normalize rhythm, or prevent thromboembolic complications associated with electrical abnormalities.
Additional treatment options
Electrophysiology study and ablation
Invasive cardiac catheterization to map abnormal electrical pathways and perform radiofrequency ablation to eliminate arrhythmia focus.
procedureArrhythmia trigger avoidance
Lifestyle modifications including caffeine reduction, alcohol limitation, stress management, and avoidance of known arrhythmia triggers.
lifestyleCardiac physical therapy
Supervised exercise program to improve cardiovascular conditioning while monitoring for exercise-induced arrhythmias.
