There are several ef-fective stretches that will help the inci-sion heal properly. ♥ Arm raises — forward: In a sitting position, straighten your arms, and raise them over your head. ♥ Pectoral stretches: In a sitting po- sition, begin with your hands on top of your head, and push your elbows back until they are in line with your hands. Relax, bringing elbows slightly forward. ♥ Arm raises — side: In a sitting po- sition with your arms at your sides, straighten your arms and raise them over your head. Keep your palms up. ♥ Sideways body bends: Place your feet about 11⁄2 feet apart for bal- ance while sitting in a chair. Bending slowly sideways at your waist, reach your right hand up- ward towards the ceiling and lower your left hand towards the floor on the left side of your chair. Hold for three seconds. Return slowly to sitting position. After these light exercises have beenperformed, check your pulse. Within a week or so, many patientshave progressed to taking walks outside.Within a month, they can often walk amile or two without difficulty. Driving,however, is not recommended for the firstseveral weeks after heart surgery. I mustadmit, however, that one of my patientsowned his own eighteen-wheeler tractor-trailer rig, and I found out when he camein for his routine postoperative visit fiveweeks after the heart surgery that he hadgone back to driving his rig across thecountry a week after he returned homefrom his heart surgery. Clearly, we don’trecommend this. 245
