Brief Answer:
abnormal heart rate/rhythms rare side effect

Detailed Answer:
HI, thanks for using healthcare magic

Sinemet is a combination of levodopa and carbidopa.

Paroxysmal atrial tachycardia is a type of arrhythmia (abnormal rate or rhythm of the heart).
Abnormal rate/rhythms may also be called palpitations

This medication very rarely causes palpitations though they are possible. It is thought that they may occur in 0.1% to 1% of persons who use this medication.

This means that 1 out of 100 to 1 out of 1000 persons who use it may have some abnormal heart rhythm though it may not necessarily be paroxysmal atrial tachycardia, maybe another type.

I hope this helps, feel free to ask any other questions

Hi...My relative had intense coughing and sputum in his blood 6 months back.He got admitted....got x rays blood reports Pleural Effusion test CT Scan,Pet Scan, , and finally needle biopsy left lung......in that order. Only test positive was pleural effusion for TB,rest all were negative. For Biopsies, got slides analyzed from 3 places.....no cancer etc. So doctor advised to continue with TB treatment.All the while in last 6 months arrhythmia was there....not severe...but was there. Since last couple of weeks hs is experiencing vertigo(guess due to arrhythmia). Anyways TB follow up was due, so got all the blood/urine reports. All normal. Got Chest Ct Scan which did not show any improvment in white spot on the lung. Almost Same size etc.No growth in spot size though.

So Question is? What is causing arrhythmia ? Biopsy was done very close to heart.Also the CT scan shows no improvement yet? Major concern is Arrhythmia which is affecting mental state of patient?

Mom is 90 years old, hospitalized for heart attack May 26. She is now taking digoxin .125 mg, enalapril 5 mg, furosemide 20 mg, metoprolol 12.5 mg, potassium 20 meq, synthroid 88 mcg. Her blood pressure and heart rate is so low that her home machine won't register it. Took bp at grocery store: Wednesday 91/33, heart rate 71; Thursday 69/34, heart rate 0. Checked heart rate at home on finger device: 70-74. She also has arrhythmia (ongoing before heart attack). She feels terrible, very low energy, no appetite, diarrhea. Research on meds indicate conflicts e.g. furosemide and digoxin; enalapril and furosemide. What is your opinion of this med cocktail?

I have been taking 40mgs of celexa and 100mgs of Lamictal for my bipolar disorder for over 2 years. I was also born with 2 heart defects: ventricular septal defect and mitral valve prolapse. Over the last two months, I have developed an arrhythmia that occurs several times an hour. I'm waiting for the results of my echo, stress test, etc. (done yesterday). Question: What is the likelihood that I'm experiencing side effects of my medication? I've never had any other problems in the years that I've taken Celexa or Lamictal, but I want to make sure I treat this arrhythmia soon. (btw, I'm 32 yrs old) Thanks!

I am almost 60 years old. When I cut the grass (self-propelled mower) walking at its max speed, I get very fatigues, short of breath, and experience tightness in my chest. I use a treadmill 5 days a week and may need to lose 20 pounds. I had a stress EKG 2 years ago and everything was fine. I have high BP, controlled with medication and Type 2 Diabetes controlled with medication. Many times I get arrhythmia during these events. What could this be?

I was diagnosed with attrial flutters ( arrhythmia ) and the cardiologist did a cardio version and a subsequent EKG showed the condition was corrected. The doctor has me on Xarelto and a beta blocker . I feel fine and I am wondering if I can drink...

I recently had an echo and stress test due to abnormal EKG following six months of FOLFOX chemo. I was told I have RBBB and a shadow at and behind the tip of my heart. I asked if it were a possible metastasis as I have an inherited cancer...
