Cardiac Meds
Block catecholamines, decreases myocardial oxygen demand/needs
Beta Blockers
HR x SV
Cardiac Output
P-R - 0.12 -0.20
Rate 60-100
R-R regular
P-P Regular
Sinus Rhythm
Chest pain
Angina
This causes peaked T waves
Hyperkalemia
Cause the heart to slow, and vasodilation. Prevent calcium ions from entering certain cells
Calcium Channel blockers
the phase of the heartbeat when the heart contracts and pumps blood out.
Systole
No P waves
Regularly - irregular
Atrial Fib (A-Fib)
Heart Attack
Myocardia Infarction
100/70 MAP?
80
It prevents the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor (blood vessel-narrowing) hormone. By blocking this conversion, these medications lower blood pressure and improve blood flow.
ACE inhibitors
Resistance to blood being pumped from the LV. Often called SVR
Afterload
Fine, erratic, no cardiac output. NO Ps NO QRS
Ventricular Fibrillation
Diastolic Heart Failure
Heart Failure with Preserved Ejection Fraction (HFPEF)
Lab indicating overdistension or stress of the Left Ventricle
BNP
This medication is used for a local anesthetic as well as an antiarrhythmic. Can also be used for pain.
Lidocaine
Percentage of blood pumped with each beat
Ejection fraction
No P waves seen
Regular R-R
Wide QRS
May or May not have cardiac output
Rate Greater than 100 BPM
Ventricular Tachycardia
Brain attack
Stroke or CVA
Most specific lab for myocardial damage
Troponin
Medications used to treat irregular heart rhythms. They work by restoring or maintaining the normal electrical conduction system of the heart,
Antiarrhythmic
Left Ventricular End diastolic pressure
Preload or wedge pressure
No cardiac output
Confirm in 2 leads
No P, NO QRS, Rate = 0
Asystole
Normal Sinus Rhythm with no cardiac output
Pulseless Electrical Activity (PEA)
Test to look at wall movement and valve function
Echocardiogram
