Heart attack
Also called: myocardial infarction

Older man clutching at his chest, experiencing pain and tightness. Close-up of a blocked coronary artery and muscle affected by lack of blood supply in the heart.

 stroke is when a blood vessel that brings oxygen and nutrients to the brain is either blocked by a clot (an ischemic stroke), or it ruptures (a hemorrhagic stroke), which cuts off the vital blood and oxygen flow to that part of the brain.
***The Right side of the brain controls the left side of the body and vice versa...so a Right side of brain stroke affects the left side of the body-Memorize mnemonic below!

Also called: CVA, cerebrovascular accident

***EXTRA CREDIT ASSIGNMENT ON MY PAGE DUE TOMORROW!!!

Oxygen diffuses from maternal blood to fetal blood through the placenta. Within the womb, the lungs are not able to work properly and so blood is rerouted through the foramen ovale and the ductus arteriosus. The liver is also underdeveloped, and not ready to perform the functions it will do in adulthood. The placenta takes over for the liver during gestation, and so blood is shunted away from the liver by the ductus venosus. This prevents oxygen that could be useful in other places from being wasted in the liver.

Procedures
  1. To begin blood pressure measurement, use a properly sized blood pressure cuff. ...
  2. Wrap the cuff around the upper arm with the cuff's lower edge one inch above the antecubital fossa.
  3. Lightly press the stethoscope's bell over the brachial artery just below the cuff's edge. ...
  4. Rapidly inflate the cuff to 180mmHg.

***Key Vocabulary:
The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract(heart strings)

EKG Waveform

ekg waveform component names

The P Wave

The first deflection is the P wave associated with right and left atrial depolarization

The QRS Complex

Typically this complex has a series of 3 deflections that reflect the current associated with right and left ventricular depolarization

The T Wave

The T wave represents the current of  ventricular repolarization

***Depolarization = contraction = systole...

***Repolarization = resting = diastole...

Ventricular fibrillation (V-fib )... is when the heart quivers instead of pumping due to disorganized electrical activity in the ventricles.

Random students so all be prepared(a class rule)...
***Cardiac Cycle: text p. 372...The cardiac cycle is the sequence of events that occurs when the heart beats. ... In the systole phase, the ventricles contract and pump blood out of the heart and to arteries.Relaxation is Diastole... One cardiac cycle is completed when the heart chambers fill with blood and blood is then pumped out of the heart.
***lubb-dupp (lub-dup)  a representation of the normal heart sounds as heard through the stethoscope. The first coincides with closure of the mitral and tricuspid valves; the second with closure of the aortic and pulmonary valves.

***Cardiac Output: Text p. 373...the product of the heart rate (HR), or the number of heart beats per minute (bpm), and the stroke volume (SV), which is the volume of blood pumped from the ventricle per beat; thus, CO = HR × SV. Values for cardiac output are usually denoted as L/min.

Sample problem: If Jenny has a resting heart rate of 60 beats per minute and a stroke volume of 70mL, what is her cardiac output?

Thursday-2/21...CW: Cardiac Output-short video

***Verbal Heart blood flow skill begins today-
Criteria:1-2 min. duration...No mistakes...
HW: Ch 11 Formative quiz 3...

***Myocardial Infarction = M.I. -a heart attack where myocardium heart muscle is starved of O2 so it develops an 'infarction'...an obstruction of blood supply...

***The cardiac output is simply the amount of blood pumped by the heart per minute. Necessarily, the cardiac output is the product of the heart rate, which is the number of beats per minute, and the stroke volume, which is amount pumped per beat. CO = HR X SV. The cardiac output is usually expressed in liters/minute. If given the Hr and need to find stroke volume, you do as always in math...reconfigure the formula for CO/HR = SV.
***normal adult has a cardiac output of 4.7 liters (5 quarts) of blood per minute.

Here’s an example:
If a patient's stroke volume is 75 mL with each contraction and his heart rate is 60 beats/minute, his cardiac output is 4,500 mL/minute (or 4.5 L/minute).
ALL UNITS MUST CORRECT...
