pressure
Which node is located at the junction of the superior vena cava and the right
atrium, is typically supplied by the Right Coronary artery, and fires at a rate of 60-
100 bpm.
SA Node
Atrial depolarization characterized by smooth, round, upright deflection less than
0.11 secs long and less than 2.5mm tall is referred to as what on the ECG?
P wave
Carvedilol (Coreg)
Metropolol (Lopressor)
Atenolol (Tenormin)
Propranolol (Inderal)

Acebutolol (Sectral)
Comolol (Brevibloc)
Beta Blockers - used for blood pressure and cardiac problems
Epinephrine
Norepinephrine
Vasopressin
Dopamine
Phenylephrine
Dobutamine
Vasopressors
The middle of phase 3 to beginning of phase 4 in the cardiac cycle where cardiac
cells are partially refractory and partially repolarized and certain cells can be
depolarized in response to electrical stimulus.
Relative Refractory Period
(Partial flush of the toilet)
Starlings Law
When end diastolic volume increases, stroke volume increases as well.
(When more blood is in the ventricles, the cardiac muscle stretches like rubber band
and creates more forceful contraction)
Intrinsic Rate for Ventricles (Purkinje Fibers)
, 20-40
Intrinsic Rate for AV Junction
40-60
Treatment for Beta Blocker Overdose
Glucagon: 1-5mg IV/IO (1st Line Drug)
Calcium Chloride: 500mg - 1g IV/IO
Why do we give Nitro for chest pain?
Class
MOA
Indications

Relaxes vascular smooth muscle = vasodilation and venous pooling which Reduces
Preload/Afterload and Dilates Coronary Arteries which increases myocardial perfusion.
Cardiac Chest Pain
Acute Pulmonary Edema
What is our dose for nitro, and what are the contraindications?
0.4mg sublingual
15mg/1inch paste
1g patch
Systolic <90mmHg
PDE5 inhibitors x 48hrs
Head Trauma/Hemorrhage signs
Poor Systemic Perfusion
Swelling of affected limb, pain and tenderness, inflammation/redness, warm to
touch on affected limb, pain on dorsiflexion (Homan Sign) are all signs of?
DVT
Treatment of DVT
Supportive Care, Position of Comfort, Establish IV, Cardiac Monitor, Pulse Ox, O2,
Monitor vitals for embolism.
Do not massage affected limb.
The pressure gradient that drives coronary blood pressure.
The difference between aortic diastolic pressure and left ventricular end diastolic
pressure that perfuses the coronary arteries.
Coronary Perfusion
Tachycardia, Difficulty Breathing, Diminished Lung Sound, Pulse Quality
Changes, and unequal chest rise are early signs and symptoms of?
Tension Pneumothorax
Air is entering the pleural space but cannot escape. Positive pressure ventilation can
make it worse.
