Study Notes
Cardiac Catheterization & Patient Assessment
- Immediate action is necessary if there are signs of compromised blood flow, such as colder toes on the catheter insertion side or absence of a pedal pulse.
- Contact the doctor immediately and prepare the patient for potential return to the catheterization lab if complications arise.
Cardiac Electrical Conduction
- Electrical conduction begins at the SA node, which is critical for initiating heartbeats.
- Calcium (Ca²⁺) plays an essential role in the heart's electrical activity.
Heart Anatomy & Function
- Patent foramen ovale (PFO) is a common fetal structure that may remain open after birth, affecting 1 in 3 or 4 individuals.
- A normal ejection fraction is between 55-70%, indicating good heart function.
ECG Basics
- A ventricular rate is determined by measuring the R to R intervals on the ECG.
- Misconception that 12 lead ECG requires attaching twelve leads; actual practice may differ.
Heart Sounds & Pharmacology
- The first heart sound during auscultation corresponds to the closure of the atrioventricular valves, signaling the beginning of ventricular contraction.
- Medications such as digoxin and labetalol can lower heart rate, influencing cardiac output.
CPR Guidelines
- During CPR, ensure compressions are at least 1/3 of the chest volume to be effective in maintaining circulation.
Emergency Response
- In cases of severe chest pain, especially with descriptions like "an elephant sitting on the chest," an immediate call for the code team and crash cart is essential to provide prompt care.
Medication Effects
- Medications ending in "INE," such as certain beta-blockers, typically decrease heart rate, impacting cardiac workload.
