Would echo,ekg,stress test,xray,bloodwork rule out any arrhythmia problem such as premature ventricular contraction and paroxysmal atrial fibrillation?

Would echo,ekg,stress test,xray,bloodwork rule out any arrhythmia problem such as premature ventricular contraction and paroxysmal atrial fibrillation?

No: Occasional PVCs are normal. Paroxysmal atrial fibrillation by definition is only present some of the time and the tests you list could easily miss this if done while the heart is in normal rhythm. Diagnosis of intermittent arrhythmias can be difficult and frequently requires consultation with a cardiologist subspecialized in electrophysiology, Holter monitor test is frequently used. ...Read more

Abnormal Heart Rhythms (Definition)

Abnormal heart rhythm is a condition in which a person has an abnormal heartbeat pattern, as detected by an EKG (electrocardiogram) of the heart. Some abnormal rhythms run in families (hereditary abnormal rhythms). Some abnormal rhythms are not dangerous, while others can cause ...Read more

Ecg , cardiac echo, heart enzyme , chest ct, cardiac angio ct, all ok.Still resting heart pulse 53-62.Increase when move.Exclude cardiac issue?

Normal : Low heart rates w/out symptoms can be nl in healthy active individuals. The fact that ur hr increases w/ movement is helpful and points towards normalcy. ...Read more

Can cardioversion correct an abnormal heart rate and rhythm?

Can cardioversion correct an abnormal heart rate and rhythm?

It can : Cardioversion can be used to correct an abnormal rhythm such as atrial fibrillation. Sometimes, however, the procedure does not correct the situation. In such cases, medications may be necessary. ...Read more

Does an holter montior detect cardiac arrythmias?

Does an holter montior detect cardiac arrythmias?

Holter monitor: Yes, but even better are monitors that you can wear for 2 - 4 weeks as they may pick up arrhythmias that may not show in a 24hr holter. ...Read more

Why is asystole (i.e. flatline) a non-shockable heart rhythm?

Why is asystole (i.e. flatline) a non-shockable heart rhythm?

No rhythm to reset: Shocking the heart resets the electrical system of the heart. In asystole, there is no electrical activity to reset. ...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

Hollow chest cavity , racing heart rate, murmur. Related?

Maybe: Pectus excavatum is more common in folks with marfan-like illness, who in turn are more likely to have "barlow" degenerative mitral valve disease which in turn predisposes a person to supraventricular tachycardia. Your physician may give you an rx, but ask also about getting into really good aerobic shape to manage the svt -- generally this works great and may keep you off meds. ...Read more

Is cardiac catheterization intrusive?

Is cardiac catheterization intrusive?

Yes: It's an invasive procedure in which a catheter (small tube) is inserted in an artery (blood vessel) in your wrist or groin, then fed backwards to your heart in order to take pictures of the heart arteries. ...Read more

Would paroxysmal atrial fibrillation cause mental impairment?

Would paroxysmal atrial fibrillation cause mental impairment?

Yes: Paroxysmal atrial fibrillation (afib) refers to a brief episode of irregular heart rhythm that may cause a variety of symptoms including confusion, palpitations, sweating, chest pain, nausea, vomiting, and sometime even stroke symptoms including changes in language, facial drooping, weakness, and numbness to name a few symptoms. It is important to be seen by a doctor to have a complete exam. ...Read more

What is cardiac arrhythmia? Is cardiac arrhythmia partly caused by water intoxication?

What is cardiac arrhythmia? Is cardiac arrhythmia partly caused by water intoxication?

Abnormal heartbeat: The normal heartbeat is from the sinus, located in the top of the heart and is called normal sinus rhythm. An arrhythmia is anything other than sinus rhythm - supraventricular tachycardia (svt), atrial fibrillation, atrial flutter, ventricular tachycardia are all cardiac arrhythmias. They can cause fainting and worse, up to and including death. Water intoxication does not cause them. Alcohol can. ...Read more

Cardiac Arrhythmia (Definition)

The normal heart beat starts in the sinus node of the right atrium. An arrhythmia is when the heart beats too fast, too slow, starts in a different place, or if the electrical activity of the heart circulates through a different pathway ...Read more
