Anatomy
Volume of blood ejected by ventricles in one minute.
What is cardiac output?
This node has an intrinsic rate of 40-60 BPM.
What is AV node?
Inflammation of the outer layer of the heart
What is pericarditis?
On a rhythm strip this interval measures the time and impulse it takes to travel from the atria to the ventricles.
What is the PR interval?
This type of map is shown in the attached image.
What is a voltage map?
Specialized areas that detect changes in blood pressure in the walls of the aorta and internal carotid arteries
What are baroreceptors?
Phenomenon by which cardiac cells can generate impulses without external stimuli.
What is automaticity?
Localized dilation and weakening of an arterial wall
What is an aneurysm?
This ECG finding presents with an upward and wide deflection of the QRS complex with two distinct R waves
Right Bundle Branch Block
The directionality of the arrythmia in the associated image
What is CCW?
Labeled 4 in the attached image.
What is the circumflex?
Where the main delay occurs in the cardiac depolarization process.
What is the AV Node?
Most common cause of mitral stenosis.
What is rheumatic heart disease?
This cycle length corresponds to a heart rate of 200bpm.
What is 300ms?
What is demonstrated by the map in the associated image?
What is medial to lateral CTI block?
Largest cardiac valve
What is the tricuspid valve?
This is the normal conduction sequence within the cardiac conduction system.
What is the..... SA Node->Inter-atrial tracts (BB)->AVN->Bundle of His->Right and Left Bundle Branches->Purkinje Fibers.......?
This condition may lead to volume overload of the left atrium and ventricle.
This lead utilizes the left arm(-) and left leg (+).
What is lead III?
Where the physician would likely ablate first based on this map.
What is low crista terminalis?
Mechanical state of the heart at the end of diastole with the ventricles at their maximum volume.
What is preload?
Interventricular conduction proceeds from the bundle of HIS through these three fascicles.
Right bundle branch
Left anterior fascicle
Left posterior fascicle.
Most common cyanotic congenital heart condition
What is tetralogy of fallout?
This anatomic landmark is consistently found at the second intercostal space and can be used to begin accurately counting the intercostal spaces for precordial lead placement
What is the Angle of Louis?
This arrythmia is shown on the associated image.
What is a AVRT?
