The normal heart rate is really an average heart rate, around 80 beats per minute. Many things can make it go faster or slower, including activity, medication, drugs, exposure to insectisides or mushrooms and others. A slow heart rate is called bradycardia, usually around 60 beats per minute. Sometimes the electrical nodes in the heart which help to make the heart start a new beat quit or work incorectly. In these cases medication or a pacemaker are required. I hope this answers your question.

Check out this manual of the Omron heart Rate Monitor. It will help you in solving your problem.

change you "HR view" to HR, not HR%. Currently you are seeing your heart rate as percentage of your Max Heart Rate (Max HR) but not by beeps per minute (bmp). Go in to the settings and see HR View.

For Sportline 915 all you have to do to turn on the heart rate feature is to press the reset button on the lowe right and put your finger on the meatl part. A heart will appear on the top right of the screen indicating that the feature is on.

Check that the case back is on the right way. A spring sticking out of the watch mech needs to line up with a hole in the white sticker on the inside of the case back, I think this is the receiver aerial.

Heart rates are known by the garmin software as zones, numeroted 1 up to 9.
You can set on the software your heart rate, based on :
- HR max ;
- intermediate HR, linked to the zones.
Then, when you upload a session in the software, you will analyze the zones you ran in.

Another tip : to set on the Garmin itself, the Zones to ON,then Z0 to ON, and Z0 HRM to ON : here you can indicate your HRM low (ex : 165 for me) and the HRM High (185 for example). Then during your session, an up or down arrow will appear, indicate if you run below your HRM low (aerobic zone), your anaerobic zone (betwin HRM Low and High) or in VO2 max.

Hoping that's clear and that can help you.

Here are the things I have noticed that help:
- enough moisture between the HR monitor and your chest. Apply water right before your workout to make sure it isn't all dry between the time you put on your monitor and when you actually started your workout.
- Make sure the strap is tight enough. Mine gets loose over time and the bouncing of running will give me inaccurate readings until I tighten it up again. You can test if this is the problem by using your hands to press the monitor more tightly against your chest - if that seems to fix the problem that a loose strap could be it.
- Use a "conductive gel" instead of water between the monitor and your chest. Conductive gels are pretty cheap.
