WebInotropic agents are a group of medicines that affect the contraction of the heart muscle. Technically, inotropes can be divided into positive inotropes, which stimulate and increase the force of contraction of the heart muscle, and negative inotropes, which weaken the … WebThe positive inotropic impact of increased intracellular Ca++ is what causes this effect, which ultimately results in an increase in both heart rate and force of contraction. 7b. The mechanism by which Ca++ action on heart rate and contractility is mediated is the increase in calcium release from the sarcoplasmic reticulum.
WebAug 1, 2024 · Inotropic and vasopressor agents are a mainstay of resuscitation therapy during cardiopulmonary arrest. 53 Epinephrine, with its potent vasopressor and inotropic properties, can rapidly increase diastolic blood pressure to facilitate coronary perfusion and help restore organized myocardial contractility. WebCardioinhibitory drugs depress cardiac function by decreasing heart rate (chronotropy), myocardial contractility (inotropy), or both, which decreases cardiac output and arterial pressure. These cardiac changes reduce the work of the heart and therefore decrease myocardial oxygen consumption .
