Detailed Answer:
Hello again, dear XXXX!

Welcome back on HCM!

Regarding your heart rate, I would explain that it is true that 54 bpm is considered bradycardia but is just slightly below 60 bpm. So, it is not considered an extreme bradycardia.

During resting conditions, sinus bradycardia is frequently found especially in relatively young adults.

You shouldn't worry about that number value!

Now, returning to the concern about the heart rhythm during that monitoring, I would explain that it is difficult to determine the exact underlying rhythm without an ECG monitoring.

Regarding wandering pacemaker rhythm, I would explain that bradycardia is not a necessary condition for its appearance. I may appear in a normal heart rate and also high (above 100 bpm). It is noted by the different P wave patterns from beat to beat on the registered ECG.

The only issue to be concerned about bradycardia would be if it is persistent and a proportional increase of heart rate with exercise load doesn't occur.

If such is the case, suspicions about sick sinus syndrome are raised. But, to come in such a conclusion extensive study of ECG is necessary through Holter (rhythm) monitoring and exercise stress testing (in case the heart rate doesn't increase sufficiently).

Thar's my opinion.

Hope to have been helpful to you!

In case of any further questions, feel free to ask me again!

Kind regards,

Dr. Iliri

Okay!
I am truly impressed. Do you always work?.? Its saturday night and you still answer questions. Its almost like the site has just come up with a name and multiple people or å machine is answering.

So. If i am able to raise my heart rate when doing something like walking stairs to 100 bpm it would not be a pacemaker rythm or replacement rythm?
I get you have to study an ecg for it.

But it måkes sence to me. Rbbb. Lightheaded. Low heart rate all Which i have.
Also it responds poorly to stuff like standing from sitting, stimuly like shocks, frights etc when i WANT it to beat fast, but it often beats slower and harder, and really ukomfortable for two seconds. U know?

I am overusing your service i know. But i really feel we might be on å track to solving this. Imagine that. An Internet doc would be crucial to diagnosing and solving a thing that has måde my life shit for 20 yrs...
I would owe å person i never met more gratitude than possible to imagine. I have recommemded you to several groups on Facebook. People need help. And search for answer. Like me. And you provide with exellence.
I know fit people can have low rest pulse. I am very thin but not fit. So my low rate is absolutely not because of good shape.

Brief Answer:
My opinion as follows:

Detailed Answer:
Dear XXXX,

I already know that you have experienced several unpleasant feelings recently (lightheadness, dizziness, weakness, etc.) and as I have already explained to you even during our previous threads, this situation could be related to several possible cardiac or extra-cardiac issues.

If we were to focus on potential cardiac issues, first it would be necessary to exclude or confirm any cardiac structural abnormalities. In this regard cardiac ultrasound results would be important. As they are normal, there is nothing to worry about. If the results from trans-thoracic echocardiography were not sufficient, then a trans-esophageal echo (TEE) could be helpful to detect very small changes not observed with the previous techniques.
Then the next point of interest would be investigating potential cardiac rhythm or conductance abnormalities.

Coming to this point, the so called “wandering pacemaker rhythm”, that you are interested about, couldn’t be an explanation of your complaints, because first of all it may be present not only in bradycardia (low heart rate), but also normal heart rate and even tachycardia, as I explained to you.

So, we don’t have to think first of “wandering pacemaker rhythm”, when we see low heart rate.

What concerns me most is whether your heart rate modulation is weak (that is the cardiac response during several stressful daily conditions by modulating and changing the heart rate) secondary to the body requirement).

So, as you are saying that your heart rate doesn’t increase too much from sitting to standing and in several other physical conditions, then it is a matter of concern, as we have to exclude first the Sick Sinus Syndrome (a sinus node dysfunction).

In this regard, it is necessary to carefully explore the vegetative nervous system modulation and also cardiac rhythm and conductance by means of Holter monitoring and also the heart rate response during exertion, be means of cardiac stress test.
So, to conclude and make it clear for you:

-After checking carefully for a cardiac structural abnormality, trans-thoracic and trans-esophageal cardiac echo.
- It is necessary to investigate cardiac rhythm abnormalities and possible atrio-ventricular conductance impairment. Coming to this point, first to be excluded is Sick sinus syndrome.
- At the end other extra-cardiac causes should be excluded (possible autonomic nervous system dysfunction, adrenal gland dysfunction, recurrent hypoglycemia, thyroid dysfunction, etc.).

You should discuss with your doctor on the above issues.

Hope you will find this answer helpful!

Regards,

Dr. Iliri

Brief Answer:
I would be glad to review your reports.

Detailed Answer:
Hello again!

I would be glad to review your Holter monitoring report whenever you will upload it!

I would just recommend trying to provide the whole Holter recordings and final analysis in Word format or PDF, because it is easier for you to upload that way and also for me to review here.

Let me know about everything!

Wishing all the best,

Dr.Iliri

Hi Ilir!
Just wanted to say that today I am wearing Holter. And I am embarresed to say, but during "sexual Activity" as I Close to climax(orgasm) when adrenaline set in, I had a long run of chatotic heartbeats. It felt like "if it doesnt find a rythm soon, Ill drop dead" boblebliboblibop! I read online that some others experince same during masturbation. So I am not the only one!
So thats good right? Now this is FINALLY registered, it should be possible to see if this is Dangerous or benign, etc. So I will ask tomorrow if the are able to give me a transcript for you to look at?

Detailed Answer:
Hello again Dear!

It is OK to have some ectopic heart beats during sexual activity and orgasm. It happens to every healthy individual.

But, I agree with you that this is a good chance to know if it is a benign or dangerous type of cardiac arrhythmia, as it has been registered.

I would be happy to review those reports!

I remain at your disposal whenever you need!

Regards,

Dr. Iliri
