(Heart attack) Usually caused by atherosclerosis, often with a thrombus attached: Step 1. A thrombus may obstruct one of the coronary arteries supplying the heart. Step 2. Vasospasm may occur in an artery that is already partially obstructed. Step 3. Part of the thrombus may break off, can form an embolus. After obstruction, necrosis of the heart tissue occurs, causing inflammation and ischemia. Necrotic tissue will eventually be replaced by fibrous tissue about a week post MI - nonfunctional tissue. The heart can develop "collateral" circulation to compensate. |
Myocardial Infarction |
|
|
The major cause of death following a heart attack, usually within the 1st hour |
Arrhythmias |
|
|
If the Left ventricle is impaired, reduced cardiac output leads to a lack of O2 (oxygen) |
Carcinogenic shock |
|
|
If a ventricular contraction is reduced, the volume will decrease, leading to decreased cardiac output |
Congestive heart failure |
|
|
A normal heart beat, both with respect to the heart rate & rhythm heart rate will fall between 60-100bpm |
Normal Sinus Rhythm |
|
|
Slow heart rate |
Bradycardia |
|
|
Rapid heart rate (100-160/bpm) |
Trachycardia |
Trac - rapid/fast runners causes rapid fast heart beats |
