Echocardiograms have become very detailed and relieving in the last couple of years. Hopefully they will become cheap enough to where you can get them at an annual physical.

Karelia Pro costs $100 to buy but you must sign up for the $15/month plan to have a cardiologist review the readings. The author of this article, Dr. Pearson, says the instrument is good for monitoring Afib and assessing palpitations, premature ventricular contractions, tachycardia, and other problems.
Skeptical Cardiologist: Do Mobile Heart-Monitoring Devices Work?
OMRON makes excellent blood pressure monitors. Last year they introduced a combination BP monitor + EKG, the first to measure for both high blood pressure and atrial fibrillation, two different risk factors for stroke.
Here’s a review of portable ECG instruments from 2018 (already getting out of date) that has good information. The author points out “ Many handheld ECG devices give only limited information as compared to conventional 12‐lead ECGs. Hence, concerns about their accuracy and reliability need to be examined. As information obtained by ECG invariably needs to be interpreted along with clinical inputs, it is debated if out‐of‐hospital use will really be beneficial.”

Here’s another on-going review and comparison of mobile, handheld ECG instruments.
Comparison and review of portable, handheld, 1-lead/channel ECG / EKG recorders by James W Grier, Department of Biological Sciences, North Dakota State University. He started his review in 2006 and most recently updated it March 2019. Dr. Grier provides excellent advice to the layperson using one of these monitors:
For the vast majority of layperson users of handheld ECG devices, in my experience with many friends, contacts, and colleagues, you will want/need the device for a given problem such as afib, be using it while under physician/cardiologist care, and only use/need it for a relatively short period of time (generally less than a year and often even less than a month) ... until the problem has been better identified and, hopefully, solved by an operation and/or medications. Your role as a patient doing home monitoring is to to simply obtain the recordings and pass them on to your physician, not to read and understand the results, but be able to properly record and either store or immediately send them to your physician
