Can a heart arrhythmia cause a "tia"?

Not directly. Tia stands for transient ischemic attack which is usually manifest by a temporary neurologic impairment, such as loss of vision or weakness. An arrhythmia such as atrial fibrillation, can lead to clot formation. If a small clot dislodges, it can cause a TIA or a permanent injury known as a stroke.
Some. Certain types of arrhythmias can under certain circumstances.

Many causes. Anything from an extra cup of coffee, to an odd mitral valve (mine makes my heart go off like an alarm clock if i forget to exercise) to the quivering death throes of a heart in massive heart attack. Whole books are written; thankfully we can do a lot more today for hearts that beat in odd ways. Read more...

Why can orogastric intubation cause heart arrhythmia? I'm a medical student and I can't find the answer Sorry if it's not the right place for asking

Rarely happens. The answer that you are looking for is that the esophagus and the heart are both innervated by the vagus nerve, so intubating the esophagus can increase stimulation. The real life answer is that this is extremely rare. Having done thousands of upper endoscopies with heart monitoring, I have never seen it. Still must be cautious though. Good luck with school!

Could a caffeine induced day long heart arrhythmia be the cause of a stroke, added to having very high colesteron and being overwight?

Possibly. There are many loose ends in your question. Unusual for caffeine to actually cause serious heart arrhythmia but if so, typical arrhythmia would be frequent premature ventricular beats, which usually don't contribute to stroke. If arrhythmia was atrial fibrillation or flutter, then a clot in the heart could have formed leading to stroke. Focus now on controlling all risks: cholesterol, weight, etc. Read more...
Risk of stroke. Sometimes it is hard to know what the cause of a stroke was. But a day long arrhythmmia, at least if it was atrial fibrillation or atrial flutter, could be a cause of stroke. High cholesterol could increase the risk of stroke. Being overweight may affect the risk of stroke, at least indirectly. For people with elevated cholesterol, there may be atherosclerosis, this is a common cause of stroke. Read more...
