question: my husband, 56yrs, has pkd, 230lbs.  just came out of the hospital the other day...due to bleeding kidney.  now, i suspect that was caused by the cycler machine which he uses to dialyze.  bleeding that followed another cyler use the other night, stopped when he swtched to manual exchanges.  this morning, his bp is 111/70 and pulse rate is 118.  please tell us how to lower pulse rate...his pulse rate is normally low becasue hes taking lopressor.  pulse rate has been erratic the past two days since episode with bleeding.  thank you for your help.
