Block the effluent of potassium ions during repolarization phases 1-3 prolonging refractory period, decreasing frequency of arrhythmias

103
Q

Class IV anti-arrhythmic agent

A

Calcium channel blockers or antagonists, block pathways for calcium entry to excitable membranes of heart and blood vessels that develop action potentials. Deceases SA node activity slowing heart rate and conduction velocity of the AV node

104
Q

Treatment of heart disease

A

Cardiac glycosides, diuretics, vasodilators, ACE inhibitors, Beta adrenergic blockers, phosphodiesterase

A

Used to increase force of myocardial contraction without causing increase in consumption of oxygen

106
Q

Derived from digitalis purpurea or digitalis lantana plants

A

Cardiac glycoside

107
Q

Cardiac glycosides increase

A

Blood flow & kidney function

108
Q

Hypokalemia

A

Low potassium levels in the serum

109
Q

Hypercalcemia

A
