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

Flutter (Definition)

Atrial flutter is an abnormal heart rhythm in the top of the heart in which the top of the heart beats very fast but very regularly (as opposed to atrial fibrillation which is always irregular) and can lead to a rapid heart rate and ...Read more

Possible causes of heart palpitations?

Possible causes of heart palpitations?

Palpitations: These are caused by many things. Stress, excitement, irritants both physical and chemical, pressure like a hiatal hernia or esophageal push or pull, and primary heart things, the causes are very many in number. ...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 cause of supraventricular tachycardia?

What is cause of supraventricular tachycardia?

Good question: With no simple answer. There are many triggers like caffeine, nicotine, alcohol, excess thyroid hormone, anxiety, stress, decongestants eg pseudoephedrine, direct stimulants eg cocaine, etc. But you also have to have potential electrical connections in your heart that you're born with or acquire eg from rheumatic fever. ...Read more

What causes atrial fibrillation? Is stress the main cause of atrial fibrillation, and is it genetic?

What causes atrial fibrillation? Is stress the main cause of atrial fibrillation, and is it genetic?

Not Really: The main cause in ~90% of cases from young persons like you is extra heartbeats starting in structures called the pulmonary veins. Sometimes that's all it is; more often than not though, the top chambers (atria) also have dilation and scar tissue which helps sustain the fib once it starts. Only a small portion of afib is clearly known to be genetic. Stress triggers extra htbeats -?-> fib. ...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 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

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

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
