Stress Test after Holter and Tach Episode - Is Fine Now?

Seasons Greetings
In sequence of tach post 30/11 went to the Cardio.Did detailed blood & urine tests(thyroid,adrenaline,renal,endocrine,24h urine,etc.)that were fine.Did also a stress test.The results were:Stress test m

Dear Jose,

Exercise induced PVCs can be associated with increased risk for blockages in the heart arteries. If a person develops PVCs  occurring  in more than 10% of beats in any 1 minute or more than  3 beats in a row, they may be at increased risk.  PVCs may occur in approximately 1/3 of asymptomatic men performing a maximal treadmill test. A subgroup of healthy men (~2%) will have severe exercise induced PVCs which is associated with 3 times the risk of developing coronary artery disease.

MET (Metabolic Equivalent): term used characterize the oxygen uptake during an activity. The more strenous the level of exertion, the more oxygen is taken up and the higher the METs. This is used as parameter of how much a person could exercise and has been correlated with outcome. The higher the METs performed, the lower the risk. It seems as if you performed 15 METs at peak exercise, which is great.

RPP(Rate pressure product): The heart rate at peak exercise multplied by the systolic blood pressure. This is an estimate of myocardial oxygen demand and is not associated with outcome.
This is not a parameter we follow closely after a stress test.

The tachycardia you experienced is what led to the stress test, from what I understand? You may consider having a holter monitor study or wearing a  loop recorder in an effort to determine what type of rhythm is causing the tachycardia. The holter monitor is a device worn for 24 to 48 hours and the loop recorder may be kept on for approximately 1 month.  They record the heart's electrical activity and help in detecting rhythm disturbances.

The data you sent me suggest that you are in the low risk category. I think it is safe  for you to exercise. I would also discuss the tachycardia with your doctor.

Thanks for your question,
