What is nocturnal angina?
Give this one a try later!
- Occurs only at night but not necessarily during sleep
Interpret a third degree heart block.
,Give this one a try later!
- Heart rhythm: atrial and ventricular rate are regular but there is no
relationship between them
- Heart rate: atrial rate is greater than ventricular rate
- P waves: uniform and upright
- P to QRS ratio: usually more P waves than QRS complex
- PR interval: none-P wave and QRS complex are not related to each other
- QRS complex: may be narrow (less than 0.12 seconds) or wide, depending
on location of escape pacemaker ( junctional vs ventricular)
- Treatment: immediate temporary pacing (meds: atropine, epinephrine,
isoproterenol and dopamine may be used temporarily to increase HR and
support BP). Definitive treatment: permanent pacemaker
What are diagnostic tests for a patient suspected with a heart failure?
Give this one a try later!
- ECG: look for evidence for ischemia, infarction, arrhythmia (ex; a.fib)
- Chest radiography (assess for signs of PE, cardiomegaly, alternative
diagnoses (ex; pneumonia))
- Echocardiography (if the cardiac or valvular function is not known, f/u to
compare to previous)
- Exercise testing
- Stress test
- MRI-cardiac
- Cardiac catheterization
What is the zone of infarction?
Give this one a try later!
, Where cell death is happening
How long should the ST segment be?
Give this one a try later!
Deviation from baseline
What happens in phase 3 of an action potential?
Give this one a try later!
DESCRIPTION
- Repolarization
IONIC MOVEMENT
- K+ out of the cell
MECHANISMS
- Ca2+ and Na+ channels close; K+ channels remains open
What is the pathophysiological of COPD?
Give this one a try later!
Characterized by chronic inflammation found in the airways, lung
parenchyma (respiratory bronchioles and alveoli), and pulmonary blood
vessels
, What is blood pressure?
Give this one a try later!
The force exerted by the circulating blood volume on the walls of the
arteries
What is silent ischemia?
Give this one a try later!
- Ischemia that is asymptomatic
- Associated with diabetes mellitus
What are pulmonary bullae?
Give this one a try later!
Large air spaces in the parenchyma
Which leads refers to the anterior aspect of the heart? (4)
Give this one a try later!
Lead 1-4
