1. Is the treatment suggested correct?
2. Are there any risks involved with the medicines to increase heart beat rate as the upper chamber is already beating at 300 per minute.
3. Was the maze procedure which was done a failure in this case?
4. Is there any other procedure to correct this without the permanent pacemaker plantation?

Heart Disease and Heart Attack Answer A4224
Current medical status: A mitral valve defect was found for my mother (Age 45) which was confirmed by ECG reports. Along with the valve defect, an uneven heart beat was also reported. To correct all this, a valve replacement surgery was done along with a maze surgery last week. However, now it has been said that the upper chamber of the heart is beating at 300 per minute while the lower chamber is beating at 50-65 per minute.
Current medical treatment: Treatments suggested - 1. Wait in the icu for another 5 days (already 7 days are over) for the heart to become normal as the heart might have been swollen from the open heart surgery. 2. Some medicines have been given to increase the heart beat rate for the lower chamber. 3. If the rate for the lower chamber doesn't comes up in 4-5 days, a cardioversion is suggested. 4. If the cardioversion doesn't works out, a single chamber pacemaker is suggested for the lower chamber along with Quadron to reduce the heart beat rate for the upper chamber.

Given your description your mum is probably experiencing atrial fibrillation now. All the mentioned procedures can be used for treating atrial fibrillation. The problem is that maze-surgery should be the final option but was tried first and, unfortunately, probably failed. If the chambers’ rate is too slow a pacemaker is required.

This is a very specific problem that requires an expert opinion from a cardiologist.
