Wrist-based heart rate alerts – How health watches warn of danger

Why a heart rate alert is important in old age

Cardiovascular diseases are among the most common health risks for people over 60. Many incidents, such as rapid heartbeat, a sharp drop in blood pressure, or arrhythmias, often go unnoticed for a long time. A heart rate alert can provide early warning – and in an emergency, it can even save lives.

How does a heart rate alert work?

Modern health watches like the CARE Pro 4 Plus or the CARE Air 3 measure your pulse continuously. If the heart rate exceeds or falls below a pre-set threshold, the watch alerts the wearer – depending on the model, via vibration, display, or app notification.

Who is this feature useful for?

• People with high blood pressure or heart rhythm disorders
• Individuals prone to dizziness or fainting
• Seniors who want to monitor their heart rate regularly

Example: CARE Pro 4 Plus and CARE Air 3

The CARE Pro 4 Plus enables precise pulse measurement with an individually adjustable alarm – also in combination with ECG measurement. The CARE Air 3 is aimed at beginners, is easy to use, and reliably notifies the user of unusual readings.

Conclusion

A heart rate alert provides safety in everyday life – especially for people who need to keep an eye on their heart health. Kardena watches are designed to detect warning signs early on while remaining easy to use.
