Based on what you describe, noticing the heartbeat doesn't seem to be a hindrance, so I wouldn't worry about it.
Both kayagatasati, and and anapanasati, what makes them effective as a meditation technique is they give your mind a pleasant anchor, that keeps it from wandering to distracted thoughts. Whether it's awareness of body posture, breath as it is sensed in every cell of the body, sensation at the feet as you walk, (partial) jhana can be done in all of these activities. If noticing the heartbeat is relaxing and conducive to jhana, it's fine and legitimate as a kayagatasati practice. If it's relaxing, then it's fulfilling passadhi sambojjhanga pacification awakening factor.
The case where the teacher said not to pay attention to heartbeat or other body part, was because it was causing problems with those students, headache or hypertension or whatever.

kgs = body-immersed-remembering 念身
This practice involves maintaining continuous attention anchored to the physical body, or a bodily process (examples, SN 47.20, SN 35.247. Doing so guards the sense doors. Also, like 16APS
breath meditation, which is a subset of
kgs, it has the wondrous property of removing unprofitable thoughts and hindrances, since the energy required to monitor physical processes fully occupies one's attentional bandwidth, leaving no room for extraneous thoughts. Comparing MN 119 (
kgs sutta) with MN 10 (sati'paṭṭhāna sutta), the body contemplation (kāya-anu-passana) exercises listed are identical, except that MN 119
kgs also includes the 4 jhānas and their similes (AN 5.28). Where the two suttas differ, is that the refrain that follows each exercise, in MN 10 there is a set of vipassana instructions to oberve rise and fall, etc. Whereas in MN 119
kgs, the refrain instead has instructions to use the exercise to get into 4 jhānas. Interestingly, MN 119
kgs, never mentions the ubiquitous 4sp
formula at all. Surveying all the pāli sutta refernces to
kgs, it's a frequently occurring theme to use
kgs to get into 4 jhānas, or to expect that one is doing
kgs with 4 jhānas concurrently.

I have no problem at all to be aware of my breath for many hours, but I rarely notice the breathing alone. There’s always breath+heartbeat, and sometimes the heartbeat is even more intense than the breath, no matter in what position I am. And when there's a clock at the room, the heartbeat is always perfectly synchronized with the ticktock.
I exposed this question at E-Sangha one year ago, and the recommendation was “let it go”. But after all this time letting go and dont' worrying, I’m still having a heartbeat!! (lucky me
)
Could there be a hindrance in some way? It doesn’t make me feel annoyed, but sometimes I feel like I am doing something wrong, because everybody talks about “Mindfulness with Breathing” and
focusing on one single thing, but nobody says “Mindfulness with Heartbeat”.
There are many instructions about how to fight difference hindrances, they explain with detail how to deal with the most subtle feelings and thoughts, but nobody mentions the heart beat. ¿why? ¿Am I the only one that notice the feeling of the heartbeat when trying to meditate?. It's always present, so what is the meaning of "mindfulness with breathing" for me? I've even tried to focus only on the heartbeat, but I neither can isolate it from the breath.
ps: I'm not having any kind of cardiopathy disorder, it's perfectly normal.
