R94.31

Clinical Causes: Heart disease, including coronary artery disease or previous heart attack Electrolyte imbalances, such as abnormal levels of potassium, calcium, or magnesium Structural changes in the heart, like hypertrophy or enlargement Heart inflammation or infections, such as myocarditis or pericarditis Use of certain medications, including digitalis, diuretics, or anti-arrhythmic drugs Electrical abnormalities like arrhythmias or conduction disturbances Lung diseases impacting heart function, such as pulmonary embolism or COPD Electrode placement errors during the ECG test, leading to false readings

Key Symptoms: Chest pain or discomfort Irregular heartbeat or palpitations Shortness of breath Dizziness or fainting spells Fatigue or weakness Swelling in the legs or ankles No symptoms; some abnormal ECGs are found incidentally during routine exams

Diagnosis Path: The diagnosis of an abnormal ECG involves recording the heart’s electrical activity via electrodes placed on the skin. The healthcare provider interprets the waveform patterns, intervals, and amplitudes to identify deviations from normal baselines. Further diagnostic procedures, such as echocardiography, stress testing, Holter monitoring, or advanced imaging, might be recommended for comprehensive evaluation based on initial findings.

Treatment Protocols: Lifestyle modifications, such as diet changes, exercise, or smoking cessation, to improve heart health Medication adjustments to manage arrhythmias, blood pressure, or electrolyte balance Procedures or interventions like pacemaker insertion or catheter ablation for specific arrhythmias Treatment of contributing conditions, e.g., managing lung disease or systemic infections Regular monitoring of heart activity to observe changes over time
