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

Does tachy cardia or brady cardia lead to cardiac carcinoma please explain?

Does tachy cardia or brady cardia lead to cardiac carcinoma please explain?

No: Cardiac tumors are very rare. They can be benign or malignant. Most malignant tumors have actually travelled to the heart from another location. Primary cardiac malignant tumors are even more rare, and are certainly not caused by tachycardia or bradycardia. ...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

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

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

Is supraventricular tachycardia (svt) in fetus deadly?

Is supraventricular tachycardia (svt) in fetus deadly?

It depends: Whether supraventricular tachycardia (svt) causes problems in a fetus depends on how often and for how long the fetus remains in svt, and on the rate of the svt (how fast). Typically, if a fetus is having problems with svt, a fetal cardiac ultrasound will detect that the heart function is declining and there may be evidence for abnormal fluid collections (so called non-immune hydrops). ...Read more

SMC / ANALYSIS OF A 48 HOUR HOLTER SCAN FOR "RACING HEARTBEAT": Underlying rhythm is sinus. Heart rates range from 69 BPM (asleep) to 173 bpm(unknown?

SMC / ANALYSIS OF A 48 HOUR HOLTER SCAN FOR "RACING HEARTBEAT": Underlying 
rhythm is sinus. Heart rates range from 69 BPM (asleep) to 173 bpm(unknown?

More info....: The heart rate of 173 bpm is fast and meets the definition of tachycardia. The next question is what was the rhythm when your your rate was 173? So, to make this diagnosis and then decide on treatment based on this diagnosis, you need to see a cardiologist. The cardiologist can look at your monitor results and decide on what to do from here. Good luck!!!! ...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

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

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

Results of a 24-hour holter test: 9 VPC's, 381 APC's, 3 nonsustained atrial tachycardia 4-9 beats each, at 100-102 beats/min. Is this normal?

Results of a 24-hour holter test: 9 VPC's, 381 APC's,  3 nonsustained atrial tachycardia 4-9 beats each, at 100-102 beats/min. Is this normal?

Sounds: like a bit too many APC''s The reason for this , in my opinion, should be determined..(EG Cardiac ECHO) Hope this helps! BTW nothing "dangerous" but needs attention! Dr Z ...Read more
