Hello,
Thank you for your query.
A pulse rate reaching 250â300 bpm during exercise, even for a short duration of 3â4 minutes, is well above the normal physiological response to exertion â especially in a 26-year-old male. The expected maximum heart rate for your age is around 190â195 bpm; anything significantly above that warrants further evaluation.
Although you mentioned no symptoms (like dizziness, chest pain, or shortness of breath) and that the rate resolves quickly, this pattern could point toward an underlying arrhythmic event, such as:
Paroxysmal supraventricular tachycardia (PSVT)
Atrial flutter with 1:1 conduction
Less commonly, ventricular tachycardia
The fact that this has been occurring daily for the past 20 days is significant.
Regarding Hypertrophic Cardiomyopathy (HCM):
HCM typically develops over time and is often genetic in origin, not caused directly by short-term high heart rates. However, sustained episodes of tachycardia and high-output cardiac stress can unmask a pre-existing cardiomyopathy or lead to exercise-induced arrhythmogenic remodeling, particularly in susceptible individuals.
My Recommendations:
To rule out arrhythmia or any structural heart disease, I would advise:
Resting ECG
24- to 48-hour Holter monitoring
Echocardiogram â to assess for any signs of HCM or other structural abnormalities
Optionally, a cardiac MRI if echocardiogram is inconclusive
Even in the absence of symptoms, the heart rate pattern you're describing is not typical and should not be ignored.
Please consider scheduling a consultation so I can review your full clinical picture and guide you through appropriate tests and next steps. Your safety during physical activity is important â especially if you're exercising regularly or at high intensity.
Warm regards,
Dr. Romain Rajan
