So, you think doctors actually attribute such things to the vaccine?
Some, but it's really the lawyers who do. They prefer those who took the Jim Jones Jab be dead rather than alive and suing for damages. The more that live with the exact same damage, the easier it becomes for the juries to determine that yes, the Jim Jones Jab caused heart problems.
...and that the fraudulent application for the "vaccine" negates the immunity from lawsuits.
