Videos - Heart and BP

STUDENTS CONSISTENTLY FIND THE HEART AND BP SECTION TO BE THE MOST DIFFICULT.  
Students who do not absolutely understand basic cardiovascular physiology ALWAYS bomb the third test.  If you understand basics of heart and BP regulation, and can tell the difference between heart failure and angina (2 totally different problems), then you have a chance to pass this exam.  

SERIOUSLY.  I'm making my frowniest face right now.  You have to spend time learning this stuff or you're doomed.

The videos are divided into sections:

1. Crash Course A&P review:  Heart and Blood Vessels.  
2. My videos:  More CV review, intro to heart failure and a quickie look at Angina, MI and L. Heart Failure.
3. ANIMATIONS of heart failure and angina, and effect of nitroglycerin
4. Hypertension and diuretics
5. PHARM REVIEW SESSION HF vs ANGINA:  Do this AFTER seeing all of the above!!
6. Heart ARRHYTHMIAS to treat or be caused by arrhythmia drugs:  You will be responsible for learning about Atrial FIbrillation on your own.


1. CRASH COURSE A&P REVIEW:  HEART and BLOOD VESSELS (34 minutes total)

A&P Heart review anatomy circulation, systolic and diastolic blood pressure

Crash Course: The Heart Part 1



How the heart beats (basis for arrhythmia medications)

Crash Course Heart #2 conduction



Blood vessel anatomy 

CrashCourse A & P: Blood vessels part 1



Blood Pressure regulation

CrashCourse A&P Blood Vessels Part 2




2. MY VIDEOS (20 minutes total)

VERY Basic Heart Review:  Bare bones anatomy, Renin-Angiotensin-Aldosterone, and definition of Cardiac Output. 

Quick Heart Review - Dr. Boyev



BASICS of HEART FAILURE by Dr Boyev

Basics of Heart Failure



It doesn't get more basic than this:  The relationship between angina, myocardial infarction and heart failure.  There is no narration.  Just crazy circus music from the 19th Century.  Feel free to mute it.  :)

90 seconds of heart pathophysiology



3. ANIMATIONS OF HEART FAILURE and ANGINA (7 minutes total)

HEART FAILURE:  This video reviews the pathophysiology of Heart Failure and is narrated by a man with a soothing English accent.

ANGINA  Click this link to view:  Angina Animation by "Speak from the Heart"

Angina Definition and Animation




WHAT NITROGLYCERIN DOES for Angina/Myocardial Infarction

Role of Nitrate in Ischemia




4.  HYPERTENSION & DIURETICS

HYPERTENSION
Overview of drugs for hypertension

Some Hypertension Drugs



DIURETICS:  I think we cover this pretty well in class, but if you still find yourself confused about kidney function, then this might help.  A nice, well-organized review of kidney function and the various types of diuretics.  If you are new to kidney physiology, concentrate on the actions on potassium (K+) and not so much on the other electrolytes for now.

Diuretics



5. PHARM REVIEW SESSION HF vs ANGINA
Watch this only AFTER we've finished covering pp. 2-13 in the heart handout!!!

Pharm Review Session HF vs Angina




6.  HEART ARRHYTHMIAS to treat or be caused by arrhythmia drugs.

ATRIAL FIBRILLATION:  Animation by NIH:  http://www.nhlbi.nih.gov/health/health-topics/topics/af/
Atrial Fibrillation
Note:  At the end of the animation the narrator mentions heart failure;  that is a different kind of problem than the left heart failure following an MI such as we have talked about in class.  A more pertinent result of A fib is clot formation which can lead to stroke or pulmonary embolism.

ATRIAL FIBRILLATION SLIDE SHOW AT RXLIST.COM:



ELECTRICAL SYSTEM OF THE HEART:
This ten minute video reviews how the heart beats.  This will be most useful to students who have not yet taken Bio 132/232.  It describes heart anatomy, the SA node, the AV node, and depolarization/repolarization.
