Atrial Fibrillation (Definition)

A heart condition, in which the electrical activity of the heart is abnormal. This abnormal electrical signal causes the heart muscle to contract when it is not supposed to and thus blood is ...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

Paroxysmal atrial tachycardia: what are the symptoms?

Paroxysmal atrial tachycardia: what are the symptoms?

PAT: Pat symptoms are the same as any tachycardia. Palpitations, heart rushing, lightheaded, short of breath, chest pain possible, pounding sensation in chest and perhaps other sensations by individual. ...Read more

What is Paroxysmal atrial fibrillation?

What is Paroxysmal atrial fibrillation?

Irregular pulse: Paroxysmal atrial fibrillation is an abnormal heart rhythm that is intermittent (or paroxysmal), arising from the upper chambers of the heart (or atria), and is very chaotic, or irregular (fibrillating). It can cause problems because it usually drives the heart rate up too fast (giving symptoms and eventually weakening the heart) and can increase the risk of stroke. Causes of PAF are multiple. ...Read more

What is worse: ventricular fibrillation or atrial fibrillation?

What is worse: ventricular fibrillation or atrial fibrillation?

Ventricular fib: Vf is worse; it usually causes cardiac arrest which is often fatal. Atrial fibrillation, while not as severe, also has significant health risks. It increases the risk of stroke, which can be disabling or fatal. Additionally, if the af causes a fast pulse for a prolonged period of time, this may lead to weakening of the heart and cause heart failure. ...Read more

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Can atrial fibrillation with rapid ventricular beat cause ventricular fibrillation?

Not usually: Not typically; however, if you also have an accessory pathway (wolff-parkinson-white syndrome), this is a unique situation where af is known to cause very rapid ventricular activation during af, which can lead to vf. Rapid ventricular response may cause cardiac weakening over time, which in turn may increase the risk of vf. ...Read more

Atrial ectopic tachycardia vs atrial tachycardia? What's the difference?

Atrial ectopic tachycardia vs atrial tachycardia? What's the difference?

Sinoatrial node.: The normal heart rate "pacemaker" center is in the sinoatrial node, a part of the right atrium. Ectopic atrial tachycardia means that the pacemaker region (the part that is setting the heart rate) is in another location, & is acting erratically. Atrial tachycardia implies that it is the sinoatrial node that is acting erratically. They are similar, but the heartbeat starts at different points. ...Read more

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

What is more dangerous, atrial fibrillation or ventricular fibrillation?

What is more dangerous, atrial fibrillation or ventricular fibrillation?

For: Any chances to "recover" from vfib one need to be in an intensive care an hooked to an ekg. And a slim chance to live. If someone collapses on the street, help has to come in minutes to jump heart back to normal rhythm. People who go in vfib have an underlying and severe heart disease. Conclusion vfib kills a afib can be controlled, even normal rhythm may be restored. Big difference! ...Read more

Does atrial fibrillation with rapid ventricular response cause ventricular fibrillation?

Only in a Very Few: Generally, the answer to this is a very solid "no." this is a rare complication of people with another condition (on top of their afib) called wolff-parkinson-white syndrome (or wpw). In certain patients having both conditions, the top chamber is too-well connected to the bottom and can trigger ventricular fibrillation. ...Read more

How are atrial fibrillation and atrial flutter different?

How are atrial fibrillation and atrial flutter different?

Irregular/ regular: Heart rythm problem is more unpredictable in a fib. In flutter the are more predictable and regular rate. The treatment approach differs and risk of intracardiac blood clot also in that context. ...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

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

What is the difference between atrial fibrillation and nonvalvular atrial fibrillation?

What is the difference between atrial fibrillation and nonvalvular atrial fibrillation?

Afib: Afib is the most common heart rhythm disturbance that we treat as cardiologists and can occur in a number of clinical settings and in association with other diseases both cardiac and non-cardiac. Non-valvular atrial fibrillation refers to atrial fibrillation that does not occur in the setting of mitral valve disease such as mitral stenosis or mitral regurgitation. ...Read more

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
