Cardioversion vs Defibrillation Both cardioversion and defibrillation involve delivering electrical energy to the chest to alter the heartbeat. Both are contraindicated in digoxin and catecholamine induced dysrhythmias.
The normal MCH level is between 26 and 33 picograms (one trillionth of a gram) of. hemoglobin per red blood cell. A gram is a very small unit of weight (you would need. 453.359237 grams just to get one pound).
MCH and MCHC are called red blood cell indices. They measure the average amount of hemoglobin contained within your red blood cells. Don't worry about minor abnormalities in these indices. These tests really don't deserve all that much attention if your other CBC results are within normal limits.
