User :   I am looking for a second opinion on a heart arrhythmia that has become apparent for me. I am almost 40 weeks pregnant and experiencing a sensation of slowed heartbeat at times when I lay on my side (either). It has only become notaible in the last week or so, that is in the 38th - 39th week of pregnancy. I have no shortness of breath, pain or any other symptom and after a small number of these slow beats, my heart rhythm returns to what I would describe as 'normal'. It is relieved when I sit upright. Any ideas?
Doctor :   Hi
User :   Hi, I am working with my doctor on the above issue, just interested in the thoughts of someone else
Doctor :   Did you have such symptoms in the past?
User :   No.
Doctor :   Have you seen a doctor undergone an examination for this problem?

User :   Yes I have discussed this with the doctor that is overseeing my pregnancy
Doctor :  
Doctor :  
Normally the heart rate must increase during the time of pregnancy.
Doctor :  
But there can be positional variations that can cause the changes in the heart rate.
Doctor :  
If these changes are not gross then you do not have to worry.
Doctor :   Have you followed?
Doctor :  
Position and breathing can some time decrease the heart rate.
Doctor :  
Have you followed?
User :   So what has been suggested to me by my doctors is that everything is really quite 'squashed' at the moment. The baby is full term and has not engaged so I have very little space left for heart/lungs. Does this souns fiesable?
Doctor :  
This can also be the cause for the changes.
Doctor :   Engagement of the head usually happens any where between 36 to 40 weeks of pregnancy.
Doctor :  
Unengagement can cause pressure changes on the lungs.
Doctor :  
Since you at term you can wait for another week for the engagement of the head to happen.
Doctor :   have you followed?
User :   Yes, So would you agree with the prior advice I have been given that because there is no pain, breathlessness etc that there is not too much to be concerned with?
Doctor :   Yes
Doctor :  
if there are no symptoms and your heart rate do not fall below 40beats per minute and does not improve then you need not be concerned.
User :   So should I just avoid laying on my side/ positions that are inducing these symptoms, to manage this?
Doctor :  
You can wait for a week to check if the engagement happens.
Doctor :  
Doctor :  
take a position that is comfortable to you.
User :   Can you see in anyway how this may effect delivery, whether it be vaginally or c-section?
Doctor :   Have you got an ECG done?
Doctor :  
Did you have an ECG recorded?
User :   No. The baby was monitered for any resulting signs of stress and the dr was satisfied that was ok.
Doctor :   Then how did you know that you have an arrythmia?
Doctor :  
Arrythmia is diagosed on an ECG.
User :   I noticed that my heart rate was lowered in the positions that I previously described and mentioned this to my doctor who described it as bradycardia
Doctor :   Ok.
Doctor :  
You can get an ECG done with the consent of your gynaecologist.
Doctor :  
If the ECH is normal and if the engagement of the head con happen within 42weeks of pregnancy, then there are possibilities of normal delivery.
Doctor :   Have you followed?
User :   I have, thankyou for your thoughts.
Doctor :  
Do you have any other Query?
User :   No thankyou again
Doctor :
