Hi,
In my opinion, if your stress test and nuclear test are normal, then a peak heart rate of 186, may not be a cause of concern. Even in TMT test, we take 220- age in years as target heart rate. Therefore, if your age is 34, then your target heart rate should be 186. Normally >85% of target heart rate is taken as normal, if achieved without significant ECG changes.

Some patients even attain a rate up to 110% of normal heart rate, without any ECG changes. This achievement is perfectly normal & generally depicts a more healthy heart. It is also likely to be very much normal, as your recovery rate, also, appears to be in normal range.

Take care. Hope I have answered your question. Let me know if I can assist you further.

Regards,
Dr. Satnarain Bansal, General & Family Physician
