RO 363 is an effective inotropic stimulant and is a cardiovascular modulator that decreases diastolic blood pressure and pronounces increases in myocardial contractility. Ro 363 is an effective and highly selective β1-adrenoceptor agonist.
PD 122860 is a dihydropyridine with calcium channel blocking and sodium channel stimulating properties. In the rat heart, PD 122860 increased left ventricular contractility, decreased coronary resistance and altered the shape of the electrocardiogram T-wa
Pyrromecaine is a local anesthetic used for surface anesthesia. Pyromecaine has a wide spectrum of antiarrhythmic action, exerts a favorable effect on the contractility of the left ventricle, and on the myocardial blood flow following the ligation of the
