Cardiac Agents

Heart Flow

100

A drug that affects the rate of the heart

Chonotropic Drugs

200

A drug that affects the force of contractions of the heart.

Inotropic Drugs

300

Four chambers of the heart are_______________. The _____________are on the top, the ______________are located on the bottom. 

Right, Left Ventricle, Right, Left Atria

Atrias 

Ventricles

400

Supplies pressure, forcing blood through the various vessels leading to perfusion throughout the whole body. 

Contractility

500

Drugs that alter the rhythm or electrical conduction through the heart.

Dromotropic Drugs

600

The coronary arteries get most of their blood flow during relaxation phase, which is also called ______.

Diastole

Cardiac Conduction

100

Electrical Impulse starts here.

Sinoatrial node (SA Node)

200

Sympathetic Nerves release ____________. Causing adrenergic responses (accelerated). 

Norepinephrine (NE)

300

The node between the atria and the ventricles

AV NODE

400

What contributes to the contraction and relaxation of the heart?

Action Potential

500

Pacemaking and conduction throughout the heart is driven by_______________________.

Sodium (Na), Calcium (Ca), Potassium (K)

600

Deoxygenated blood flows on this side of the heart. 

Right 

Antiarrhthmic Agents

100

Restores and maintains normal__________________.

Sinus Rhythm

200

QRS Complex is also known as___________________

Ventricular Depolarization

300

The drug class that has three types:

Na Channel blocker (moderate)

Na Channel blocker (weak)

Na Channel blocker (strong)

400

Drugs that prolong repolarization. (T wave)

K Channel Blockers

500

This drug does not convert arial fibrillation to normal sinus rhythm, but does slow the ventricular rate.

Digoxin

600

Lidocain, Mexitil, Xylocain

Ib, Na channel Blocker (weak)

Heart Failure

100

This often happens due to loss of contractility or pump efficiency makes blood volume increase with in the heart. 

Enlarged Heart

200

This happens when fluid backs up into extremities due to poor perfusion and fluid retention.

Pulmonary Edema

300

This type of drug reduces fluid volume and decreases blood pressure. (Ex: Furosemide)

Diuretic

400

Drugs that decrease vascular resistance.

Vasodilator

500

Increase cardiac output by decreasing preload and afterload. (Ex: Lisinopril)

ACE Inhibitors

600

Verapamil, Diltiazem, Cardizem

Ca Channel Blockers

Other Drugs

100

Decreases cardiac workload by slowing the heart rate (B₁) and decreasing blood pressure (a₁). 

Ex: Carvedilol

Adrenergic blockers

200

This drug is given for HTN and HF. It blocks angiotensin II regardless of its origin and is less likely to cause angioedema and cough. 

EX: Diovan

ARB (Angiotensin II Receptor Blocker)

300

Greatly reduces afterload forces on the heart. There are 3 classes of this drug. 

Ex: Hydralazine, Isosorbide, Nitrates

Vasodilators

400

Lopressor, Latetalol, Sectral, Inderal, Propranolol.

B-Blockers

500

Statins, Fish Oil, Niacin

Lipid-Lowering Agents (cholesterol)

600

Chest pain that is sharp and stabbing in nature, located laterally or posteriorly is most commonly________.

Pleuritic Chest Pain (Not Angina)

Not all chest pain is heart related!
