Is smart heart monitoring technology only beneficial for certain cardiac issues? If yes, which ones?

no, benefits are not limited to cardio issues

Primarily only practically useful for new onset atrial fibrillation

It can be potentially used for several conditions.

Arrhythmias and irregular heart beat could theoretically be interchangeable, but patients with either know condition would benefit from a smart heart monitoring technology. The others would likely present with symptoms if worsening that would warrant evaluation.

Uncertain.

The device can be used as an indirect indicator of abnormal heart rate etc

there may be others, arrythmias are the most obvious one

heart rate is easiest to monitor

Maybe be beneficial for irregular rhythm and low heart rate

my best guess

The benefit from smart watches may be highest in high-risk populations. Heart Failure may be a population of particular interest.

In critical cases it is a worthwhile precaution

It measures heart rate, regularity and is supposed to measure oxygen tension but does all three unsuccessfully

Some people are unaware of an arrhythmia, and a device can alert them to an issue.

For timely correction/effort to fix

to avoid sudden death

No, I think it could help with arrhythmias as well as low heart rate. For accurate arrhythmia detection, it might require more then just a watch, possibly a paired ring or wrist band to read current on both arms.

More than one but for sure the most urgent to be treated is heart failure

some devices may assist in diagnosis of types of arrhythmias.

Need more understanding/research.

it can give data associated with heart health, helps in precious measures.

It would be difficult to separate heart failure from device failure.

I think we will need real world studies and evidence to know the answer

I would not limit the use of such devices to irregular heart beats but based on my non-expert knowledge at this time they monitor irregular heart beats such as arrhythmias and low heart rates best. I’m not sure that they are very good at measuring and evaluating aspects of heart failure and cardiomyopathy beyond this

with the technology today arrhythmias is safest to monitor

I am not sure which is the best since I do not wear any tech.

Because it represents a real and immediate risk. It seems less adequate to rise awareness and fear in mild cases.

In general, the benefit of wearing such monitors may not outweigh the risk.

it can benefits any patient with heart disease

See respons above

Poor answer structure - cannot select multiple choices!

No, there are other health risks where heart monitoring could help. For example, there is a link between the heart and pain. See Davydov, D. M. (2022). Linking the heart and pain: physiological and psychophysiological mechanisms. In R. Rajendram, V. B. Patel, V. R. Preedy, & C. R. Martin (Eds.), Features and Assessments of Pain, Anaesthesia, and Analgesia (a volume of The Neuroscience of Pain, Anesthetics, and Analgesics) (1st ed., Vol. 1(II), pp. 211–223). London, UK: Academic Press Inc.

Scientific evidence from studies.

for all of the above it is useful

I cannot say with confidence what these technologies can be used for with reliability of a designated technology like BP monitor

Emerging research is showing benefit for many conditions actually, not only ones relating to the electrophysiology of the heart.

blood pressure, resting heart rate

Apple and Fitbit appear to have decent sensitivity/specificity.

Heart diseases lead to heart failure. Therefore, heart failure is a central indicator of breakdown

See above.

It is beneficial for all of the listed conditions, however at the top of cardiac issues it would most be beneficial are arrhythmias

more than one

Sensors with high enough accuracy could help with all. (Cannot select more than one)

arrhythmias and irreg heart neat and low ht rate and carsiomyopathy
