|
Intercalated discs |
connect 2 heart muscles |
|
|
|
Angina pectoris |
Angina pectoris causes pain sensation of left side of chest , arm and shoulder. overworking , heart exceed the ability of narrow coronary vessel to supply blood the pain will diminishes shortly after resting. |
|
|
|
Myocardial infraction |
Myocardial infraction is heart attack death of tissue due to lack of blood supply |
|
|
|
The different between angina pectoris and myocardial infraction ? |
angina pectoris : pain sensation due to Myocardial infraction : heart attack due to |
|
|
|
Autorhythmic |
Autorhythmic is self excitable These cells generate an action potential that spreads throughout the myocardium, causing the heart to contract as a single unit. |
|
|
|
Ventricular fibrillation |
Ventricular fibrillation occurs when the heart beats with rapid electrical impulses. This causes the ventricles to squiver uselessly, fail to pump blood and blood circulation stops. |
2ventricular different rate |
|
|
Cardiac arrest |
Cardiac arrest usually results from an electrical disturbance in the heart. loss of heart function, breathing, and consciousness. |
|
|
|
Congestive heart failure |
Congestive heart failure is a chronic condition in which the heart doesn't pump blood as well as it should. abnormal interventricular septum |
Thick chamber do not fill enough blood Thin chamber can not pump |
|
|
What is the different betweem cardiac arrest and congestive heart failure? |
Cardiac arrest: heart failure to function die to electrical disturbance Congestive heart failure: the abnormal interventricular septum
|
|
|
|
What the connection between Atrial flutter, ventricular fibrillation and cardiac arrest ? |
Atrial flutter; abnormal beating of the heart. Ventricular fibrillation : when the heart beats with rapid electrical impulses. This causes the ventricles to squiver , lead to fail to pump bloob Cardiac arrest : heart failure to contract |
|
|
|
Atrial flutter |
Atrial flutter ( AFL ) is a common abnormal beating of the heart. |
|
|
|
Bradycardia |
bradycardia is abnormally slow heart action. |
ex: highly trained athletes |
|
|
Tachycardia |
tachycardia an abnormally rapid heart rate. |
ex: caffeiin |
|
|
What is the different between Bradycardia and Tachycardia ? |
Bradycardia: slow heart beat Tachycardia: quick heart beat |
|
|
|
PVCs |
PVCs ( Premature Ventricular Contraction) Extra, abnormal heartbeats that begin in one of the heart's two lower chambers. PVCs occur in most people at some point. |
|
|
|
what is the different between PVCs and tachycardia? |
PVCs: not serious, no need treatment. Tachycardia: the abnormal heart beat is prolong for more than 30 sec. |
PVCs occurring continuously for longer than 30 seconds is a potentially serious cardiac condition known as ventricular tachycardia. |
|
|
Ectopic foci |
Ectopic foci are abnormal pacemaker sites (outside of the SA node). They can occur within the atria or ventricles. |
Etopic pacemaker; AS node |
|
|
Auscultation |
Auscultation is the action of listening to sounds from the heart, lungs, or other organs, typically with a stethoscope, as a part of medical diagnosis. |
|
|
|
Heart murmurs |
The symptom. Abnormal heart sound. Cause by valve leakage, decrease valve flexibility or misshapen valve. Mitral valve prolapse 2 common heart murmurs are valvular insufficiency and valvular stenosis |
|
|
|
Valvular insufficiency |
valvular insufficiency is cause by cardiac valve leaks, not closed tight enough |
|
|
|
Valvular stenosis |
valvular stenosis is cause when cardiac valve is too hard ( stenosis ) to open completely. Blood flow backward ( regurgitation) |
|
|
|
The different between valvular insufficiency and valvular stenosis ? |
valvular insufficiency : can not be close completely valvular stenosis : can not be open completely |
|
|
|
Cor pulmonale |
cor pulmonale is abnormal enlargement of the right side of the heart as a result of disease of the lungs or the pulmonary blood vessels. |
|
|
|
cardiac tamponade |
Cardiac tamponade is compression of the heart caused by fluid collecting in the sac- pericardium surrounding the heart. The result of Pericarditis |
Compression reduce in volume |
|
|
Pericarditis |
Pericarditis is a swelling and irritation of the thin sac-like membrane surrounding the heart (pericardium). Lead to leak blood vessle. Cause by virus, bacteria or fungi |
|
|
|
Hypoxia |
Hypoxia is inadequate of oxygen to supply the tissue. |
|
|
|
Ischemia |
Ischemia is an inadequate blood supply to an organ or part of the body, especially the heart muscles |
|
|
|
Mitral valve prolapse |
mitral valve prolapse Improper closure of the valve between the heart's upper and lower left chambers (tricuspid valve) |
Mitral valve = bicuspid valve |
|
|
Dicrotic notch |
dicrotic notch is a secondary upstroke in the descending part of a pulse tracing corresponding to the transient increase in aortic pressure upon closure of the aortic valve—called also dicrotic wave. |
the aortic valve called also dicrotic wave. |
|
|
Isovolumetric |
Isovolumetric is during a moment when the heart valves are all closed. the ventricles contract with no volume change |
|
|
|
Transient ischemic attack |
Transient ischemic attack is is like a stroke, producing similar symptoms, but usually lasting only a few minutes and causing no permanent damage |
|
|
|
What different between Transient ischemic attack and heart attack ? |
Transient ischemic attack: no permanent damage heart attack : serious permanent damage. |
|
|
|
Varicose veins |
Varicose vein is enlarged veins, most commonly appearing in the legs and feet. they cause aching pain and discomfort or signal an underlying circulatory problem. |
|
|
|
Blood flowback |
regurgitation |
|
|
|
The name of embryo part which is develop into ligamentum arteriosum? |
ductus arteriosus |
|
