What is pathophysiology of atrial fibrillation?

What is pathophysiology of atrial fibrillation?

Incredibly complex: This still remains unknown to a large extent. We know the pathophysiology is not the same in everyone. Many people have afib as a result of frequent bursts of abnormal electrical activity in the pulmonary veins, which enter the heart and trigger atrial muscle fibrillation. However, stretching of atrial muscle can be a stimulus to trigger fibrillation, as can ischemia (limited blood flow) in some. ...Read more

Is ventricular fibrillation the cause of cardiac arrest?

Is ventricular fibrillation the cause of cardiac arrest?

One of them: It is the most common heart arrhythmia associated with cardiac arrest. It is not exact to call it the cause, since ventricular fibrillation itself has an underlying cause, most commonly coronary artery disease, but there are others. ...Read more

Cardiac arrest v.S.Respiratory failure, what's the difference?

See below: This refers in general to what the primary underlying problem is. Cardiac arrest means that the main problem was the heart, whereas respiratory failure suggests that the main problem was the lungs. ...Read more

Irregular rhythm: The heart usually pumps at a regular pace. An arrhythmia is when the heart pumps at an irregular rhythm. This can be benign or very serious depending on the type of arrhythmia. ...Read more

Why is ventricular fibrillation the most common rhythm of cardiac arrest?

Why is ventricular fibrillation the most common rhythm of cardiac arrest?

Final pathway: Ventricular fibrillation is the final step before a heart stops beating. Any heart that has not gotten enough blood flow or oxygen for a prolonged period of time will begin fibrillating followed shortly by asystole (no beating at all). In a sense, ventricular fibrillation is the final step every heart likely goes through before it stops beating. ...Read more

Describe the features of cardiac arrest.?

Describe the features of cardiac arrest.?

Heart stops: Cardiac arrest is when the heart stops beating effectively. The heart actually ceases to beat or the heart has other electrical rhythm disturbances in which the heat no longer can work as a pump. Because of the lack of blood flow to the brain, patients become comatose, and stop breathing. Unless the condition is reversed quickly, death follows. CPR can provide some protection until help arrives. ...Read more

Patho physiology of heart failure in anemi?

Patho physiology of heart failure in anemi?

--: Anemia means low oxygen carrying agents in the blood and this is then compounded with the heart effort to maintain the oxygen delivery to other organs especially the brain by increasing its cardiac output -- and in the presence of a weak heart or other stress factor such as trauma or infection, the heart is overwhelmed and congestive heart failure ensues. ...Read more

What causes heart arrhythmia?

What causes heart arrhythmia?

Many causes: Anything from an extra cup of coffee, to an odd mitral valve (mine makes my heart go off like an alarm clock if i forget to exercise) to the quivering death throes of a heart in massive heart attack. Whole books are written; thankfully we can do a lot more today for hearts that beat in odd ways. ...Read more

What causes atrial arrhythmias?

What causes atrial arrhythmias?

Many causes: First off, need an ultrasound (echo) of your heart, because structural abnormalites of the heart are the first big cause that needs to be eliminated. If your heart is structurally normal, then the other big cause for atrial arrhythmias is diet and drugs -- especially any caffeine or diet pills. Finally, sometimes it is just idiopathic -- which means we cannot find a cause. ...Read more

What causes cardiac temponade?

What causes cardiac temponade?

Cardiac tamponade: cardiac tamponade is collect of either blood , pus or fluid in sac around the heart resulting in reduction of filling of ventricles leading to haemodynamic compromise.It is life threatening condition. it can be caused by infection, injury, post heart attack, malignancy, associated with certain disorders like rheumatoid arthritis ,SLE, radiation etc. http://patient.info/doctor/cardiac-tamponade ...Read more

What causes pulseless ventricular tachycardia?

What causes pulseless ventricular tachycardia?

Not really pulseless: When VT occurs at a fast enough rate, there is inadequate time for ventricular filling, cardiac output falls, and blood pressure falls. You may not be able to palpate a pulse but an arterial line would show a waveform that is reduced in amplitude. Rate is the key. As tissue perfusion fails, acidosis, hypoxemia and hyperkalemia result leading to ventricular fibrillation and death. ...Read more

What is pathophysiologic of right sided heart failure !?

What is pathophysiologic of right sided heart failure !?

Right heart failure: The commonest cause of right heart failure is left heart failure. The causes of isolated right heart failure include primary pulmonary hypertension and pulmonary diseases associated with pulmonary hypertension. Left to right cardiac shunts cause right heart failure and mitral stenosis is another(techinically this is a left heart cause. ...Read more
