, Normal Length for PR, QRS, and QT intervals.
PR 0.12-0.20 sec, QRS 0.08-0.12 sec, and QT interval less than or = to 450 ms or half the R-R
interval
Big box on ECG readings = ___ seconds?
0.20 seconds
Little boxes on ECG readings = ____ seconds?
0.04 seconds
The mA that achieves capture is the _______ _________
pacing threshold
Defibrillation energy settings (biphasic and monophasic)
biphasic 120-200 j and monophasic 360 j
Synchronized Cardioversion energy settings for SVT or aflutter, for afib, and for
monomorphic VT (biphasic and monophasic)
SVT or aflutter-biphasic 50-100 j & monophasic 200 j
Afib-biphasic 120-200 j & monophasic 200 j
Monomorphic VT-biphasic 100 j & monophasic 100 j
Vtach treatment
Synchronized cardioversion and Antiarrhythmic such as Amiodarone (150-300 mg) and/or
lidocaine
Vfib treatment
Defibrillation also can load them up with Amiodarone
Page 2 of 20
, SVT treatment
Vasovagal maneuvers, carotid massage, Adenosine (if BP is good) 6 mg for first dose and then
12 mg for the second dose, or synchronized cardioversion
Torsades treatment
Synchronized cardioverison (if regular) or defibrillation (if irregular) and administer Mg
(treating underlying cause)
Anatomical location of Cardiac Assessment Landmarks
Pulse pressure calculation
Difference between the systolic and diastolic pressure for example 120/60 the pulse pressure
is 60!
Cardiac output normal values
4-8 Liters per minute (formula is Stroke Volume x Heart Rate)
Cardiac Index normal values
2.5-4 L/min/m2 (formula is Cardiac output divided by Body Surface Area aka need ht and wt)
Central Venous Pressure or Right Atrial Pressure normal values
2-6 mmHg or 2-8 cm H2O
Pulmonary Arterial Pressure (PAP) normal values
Pulmonary Artery Systolic (PAS) 15-30 mmHg
Pulmonary Artery Diastolic (PAD) 5-15 mmHg
Pulmonary Artery Mean (PAM) 9-18 mmHg
Pulmonary Artery Occlusion Pressure (PAOP) AKA Wedge normal values
