Which of the following is most cardio depressant
Halothane is direct myocardial depressant, decreases SA node activity and decreases hea rate. Also sensitizes the hea to the arrhythmogenic effectsof epinephrine and hence is contraindicated in pheochromocytoma. Isoflurane , sevoflurane and desflurane at required MAC does not cause much cardiac depression. They dilate the blood vessels and decreases the mean aerial pressure .
