Is this dangerous to run at 105% of max heart rate?

No, congratulations you just redefined what your max heart rate actually is. I wouldn't necessarily reset all training to use 200 as your new 100% but basically when you exceed 100% of your maximum heart rate you have (sort of by definition) established a new maximum

Today I did a hard 7km for a tempo effort and my garmin watch showed to me that I was at 105% of max heart rate for several minutes at the end.

Normally my max heart rate is 190 but I was above 200 for several minutes.

I would consider 200bpm to be close to your maximum, and certainly closes enough for training purposes, particularly if (a big IF) you were using a chest strap (since wrist HR monitors are typically not as accurate).

Is that healthy to add more than 10 bpm of maximum or is it a sign that the heart was weakened?

There is no 105% of max HR lol you probably reached like 98-99%. I don’t understand how you can believe that you ran above your maximum, as that’s just absurd and goes against all basic mathematical teachings. Your max HR is the maximum rate of beating your heart can reach. There is no “normal max HR”.

Just run baby. Stop focusing on numbers.

Some people actually train by heart rate, and successfully at that.

Not dangerous at all. I routinely go at 300% of max heart rate.

I simply defined my max heart rate to be 60 BPM and presto! my workout intensity puts yours to shame.

In addition, getting into analysis of an individual's physiological parameters is part of the allure of the sport for some folks. So on this subject, there is no correct and proper way for everybody.

Not the OP, who has no idea what he's doing, and would be better off without it

The Garmin watch take all yours runs and compute them to calculate your maximum Heart Rate.

You can surpass this maximum heart rate like i did today but this is not normal. Usually this calcul is very accurate. But it can mean something. Maybe the heart had a slight dysfunction which changed the maximum today. Lack of vitamins or something else, I don't know at all.

Some people die doing sport when their heart goes wild. I don't think it was too bad but I wanted to know this happen to others people.

+1. Some people do well using HR data, but when you're wondering if 105% of HRmax is healthy, it's time to turn off that HR monitor and just run.

Garmin Connect show the avegare % of HR and the the maximum % of HR. It litteraly says 105%.

Based on the subject I thought would be about running faster than your MHR pace which is possible (you go faster, but your heart doesn’t beat any faster).

Nobody can sustain that pace for a couple minutes at the end of a hard 7K tempo. So that’s not it.

To the OP: If you have an underlying heart condition it could be dangerous. If you’re young and healthy probably fine. Talk to a doctor if you are unsure.

This is incorrect. I tell may Garmin what my max heart rate is. The more accurate value I give it, the better it does on its prediction metrics (so Garmin says).

^^^ I would bet a lot of money your actual HR was not over 200 at the end of a tempo. Wear a HR strap if you want to incorporate HR as a meaningful metric.

One inputs what they believe to be their HRmax (along with their gender, weight, age, etc.) in the watch's 'User Profile' widget. A maximum heart rate can be determined (close enough) from a self-test, as the OP did in his hard 7km (if he used a chest strap).

I thought it was an autocalculation.

I don' t remember doing any setting on that. I will make an inquiry to understand is the setting is wrong. Thanx.

Bingo. You are welcome.
