AI Sessions (talks) with AI Gemini (Paid subscrption to Google for their more comprehensive AI Service. Cost approx. $20. per month and very much worth it as you will see. AI Mode which is its most comprehensive yet free. For doing this project I prefer using Google AI because of its reference material. Youtube.com is one "for instance." I use Chat.DeepSeek.com and have for over two years. DeepSeek.com is free. I have not tried the paid version. American dollars and the EU Euro likewise are sinking fast in "value". So, you do have to prioritize.
In the music selections, particlarly the Johnny Cash song about 'Get Rhythm' the early emphasis I want to make is about the heart rhythm.
I asked Google AI the question , Does the word arrhythmia mean essentially "without rhythm" and it replied with AI Overview "Yes, literally translated from the Greek roots ---> arrhythmia means " WITHOUT RHYTHM " Well what does that sound like, anyway, without rhythm? Click on the link you just past, WITHOUT RHYTHM (from youtube.com) and listen for yourself. A ltittle "off-beat" isn't it! the word But in modern medical practice the word arrhythmia more specifically refers to an abnormal or irregular rhythm. A complete absence of rhythm is a specific type of arrhythmia - but not what the word means in most contexts.
The literal and modern meanings • Literal meaning: The term is derived from the Greek prefix a- meaning "not" or "without," and rhythmos meaning "rhythm" or "flow". • Modern medical meaning: In practice, an arrhythmia is any deviation from the heart's normal electrical impulses that can cause it to beat: o Too fast (tachycardia): Over 100 beats per minute. o Too slow (bradycardia): Under 60 beats per minute. o Irregularly: With a "fluttering" or "skipped beat" sensation. The debate between arrhythmia and dysrhythmia Because of the discrepancy between the literal and functional definitions of arrhythmia, there has been a historical debate about whether dysrhythmia is a more appropriate term. • Dysrhythmia means "bad rhythm" or "abnormal rhythm" (from the Greek prefix dys- meaning "bad" or "abnormal"). • Despite arguments in the mid-20th century that dysrhythmia was more accurate, both terms are still used interchangeably in medicine today. The established, common usage of arrhythmia overrides its strict etymological meaning.

Most anyone who has been to a hospital to visit a friend, or you yourself have layed in the hospital bed, bored watching insipid programs on the commercial televison - divert your eyes and zeroed-in on a television screen with rows of green lines moving across the screen, if you're normal you've wondered what it was that you were actually seeing.

2026-July-7 (12:38am) All of the diagrams below which are of 2nd Ed. for the time being will remain as is in their original form. But we've come (myself & Google Gemini AI)to a much better and more constructive way to present that material and move it on up from 1975 vintage to 2026 where the new information is volumous. Things that had nothing to do with cardiology I have removed - but not deleated. I will create a site for that purpose which I have already come up with good name.
