What's this mean?

Sitting BP: 97/74 HR 89

Standing BP: 95/79 HR 123

When doing cardio last week my heart rate stayed between 149 and 189. After stopping my HR jumped to 230, and stayed around that for 30 minutes. It later lowered after I was sitting for over an hour, and my heart rate was 45.

I don%26#039;t know what my resting HR is. I%26#039;ve been getting dizzy when I stand from last night. I noticed my asthma rescue inhaler raises my HR a lot, and I took the inhaler last night.

HR above 170ish are not great for cardio workouts in the first place, but getting into the 200%26#039;s afterwards is potentially a sign of a heart problem. You most likely were experiencing atrial fibrillation. The top chambers in the heart (atria) quiver at a very fast rate, and the ventricals can respond with an increased rate as well (rapid ventricular response). This decreases your cardiac output (the amount of blood your heart pumps), which would explain your dizziness.

A heart rate of 45 is also abnormal, except in the extremely trained athlete (think Lance Armstrong). Your asthma inhaler may also be contributing to your heart changes, as many of the medications used in rescue inhalers can increase your heart rate. I would recommend seeing your primary care physician or a cardiologist for further work up. More than likely, they will set you up wtih a holter monitor, which is basically a little box you strap around your chest like the HR monitors for treadmills, that records the electrical activity in your heart. This info is then reviewed for abnormalities and trends. Hope this helps.
