Likely you have the sensor inverted on your chest strap, Tory. Next workout, simply make sure that the button is on the side face the ground. That should invert the positioning of the ECG. HTH

That’s as normal as can be given a heart transplant. Or not, it would be hard to tell. Please take a look at what NSR normal sinus rhythm looks like; p wave followed by QRS wave, then t wave. The sensors record according to the position on your chest, p is upright, r is also positive, S wave is negative, the dip I think you’re describing. It’s all about electrical activity and movement of the wave either towards the sensor (positive) or away from it, reflected as a negative wave. Your cardiologist would be happy to have the ecg and help you understand.
