These cells are responsible for setting your heart rate and only make up 1% of cardiac cells
What are Pacemaker Cells (Autorhythmic Cells)?
Blood flows based on this gradient
What is the Pressure Gradient?
This Autonomic Branch AND it's respected nerve only innervates the SA and AV node.
What is the Parasympathetic Nervous System and Vegas Nerve?
This wave represents Atrial Depole
What is P-Wave?
Reversable spastic contractions of the coronary arteries
What is Vascular Spasm?
This delay allows the ventricles to completely fill with blood
What is an AV Nodal Delay?
These blood vessels are responsible for gas exchange
What are Capillaries?
This Autonomic Branch increases the force of contraction of the myocardium
What is the Sympathetic Nervous System?
This wave represents Ventricular Depole
What is the QRS-Complex?
This heart condition leaves patients with a higher than normal resting heart rate (>100 BPM)
What is Tachycardia?
This structure allows Action Potentials to travel from cell to cell in the cardiac tissue.
What is a Gap Junctions?
The term used to describe the average arterial pressure in the systemic circuit
What is Mean Arterial Pressure (MAP)?
Modified Postganglionic Neurons in the Adrenal Medulla
What are Chromaffin Cells?
This wave represents Ventricular Repole
What is the T-Wave?
This wired mesh helps open up clogged coronary arteries for patients with atherosclerosis
What is a Stent?
These channels open up during the slow depole phase of the pacemaker potential
What are Funny Na+ and Voltage-Gated T-type channels?
The volume of blood pumped by the heart per minute
What is Cardiac Output?
Parasympathetic Stimulation on the SA Node does what to Pacemaker Potentials?
What is Longer Slow Depole and Longer Repole?
This ECG segment represents Ventricular Contraction
What is the Q-T Segment?
Condition where venous veins are weak which traps blood in veins on the leg
What is Varicose Veins?
The Lub that's apart of the Lub Dub heart sounds is caused by the closing of these valves
What are AV Vales?
These receptors are a type of stretch receptor that are used to sense pressure in arteries
What are Baroreceptors?
This Adrenergic Receptor is used by the Sympathetic system on the heart
What are Beta 1 Adrenergic Receptors?
This ECG segment represents time between heartbeats
What is the R-R Segment?
Inadequate delivery of oxygen to the myocardium can lead to what
What is Myocardial Death (Necrosis) or Myocardial Infarction?
