Hypertrophic cardiomyopathy (HCM) is usually a condition that develops slowly over time, often due to genetic reasons. It does not typically appear suddenly within a few months if your earlier echocardiogram was normal. Since you are still having symptoms like palpitations and dizziness, it is important to rule out other causes such as anxiety, dehydration,
thyroid problems, or simple rhythm disturbances.
Next Steps
Repeat an ECG and consider a Holter monitor (24–48 hrs ECG recording) to check for abnormal heart rhythms.
• If symptoms are frequent, a repeat echocardiogram can be done for reassurance.
• A TMT (stress test) can help assess heart function during exertion.
• Consult a cardiologist for detailed evaluation.
Health Tips
Most likely this is not hypertrophic cardiomyopathy developing in just 5 months, but it is important not to ignore your symptoms. Please avoid excessive caffeine, alcohol, and overexertion until your evaluation is complete. If you experience severe chest pain, fainting, or sudden worsening of palpitations, seek emergency care immediately.
