heart pounds

My heart pounds and my chest hurts in the middle of my sternum after I chop firewood swinging an axe or working hard with upper body muscles like shoveling fast. The pain doesnt last long but I have to slow down the physical for a little while I have SSS and my pacer has been in for 20 months now.

Thank you Frank I dont know how high it goes but it pounds harder and hurts in the middle of my chest. So maybe the RR should be slowed down? That kind of work would raise my HR its how hard the heart pumps. Maybe I am that much out of shape also.

Rate Response

With SSS you likely have Rate Response turned on. It senses your body movement and uses it to increase your HR during exercise. Using those upper body muscles causes a lot of movement so your HR increases. The RR sensitivity can be adjusted so the same activity doesn't drive your HR as high. My question though is whether that kind of very heavy activity wouldn't normally raise your HR quite bit. You didn't say how high it goes.

Timing

by ElectricFrank - 2012-11-23 01:11:55

Some of the setting that affect timing between atrium and ventricle pacing can can cause uncomfortable pounding. The heart is a 2 stage pump (actually 4 depending on how you look at it). To operate efficiently the atrium should fill the ventricle to optimum before the ventricle contracts. As the HR increases this timing changes.
