This was one of the first successful criminal prosecutions of a corporate executive by the Environmental Protection Agency. Murder
John Tawell, a murderer who in 1845 became the first person to be arrested as the result of telecommunications technology. Grigori Rasputin (1916; attempted, later killed by gunshot)
The Goebbels children (1945)
Stepan Bandera (1959)
Jonestown, Guyana, was the site of a large mass murder–suicide, in which over 900 members of the Peoples Temple drank potassium cyanide–laced Flavor Aid in 1978. Chicago Tylenol murders (1982)
Timothy Marc OBryan (1966–1974) died on October 31, 1974 by ingesting potassium cyanide placed into a giant Pixy Stix. His father, Ronald Clark OBryan, was  convicted of Tims murder plus four counts of attempted murder. OBryan put potassium cyanide into five giant Pixy Stix that he gave to his son and daughter along with three other children. Only Timothy ate the poisoned candy and died. Bruce Nickell (5 June 1986) Murdered by his wife who poisoned a bottle of Excedrin. Richard Kuklinski (1935–2006)
Janet Overton (1942–1988) Her husband, Richard Overton was convicted of poisoning her, but Janets symptoms did not match those of classic cyanide poisoning, the timeline was inconsistent with cyanide poisoning, and the amount found was just a trace. The diagnostic method used was prone to false positives. Richard Overton died in prison in 2009. Urooj Khan (1966–2012), won the lottery and was found dead a few days later.
The constant interval between the sinus beat and PVC suggests a reentrant etiology rather than spontaneous automaticity of the ventricle.Premature atrial contractions by contrast do not have a compensatory pause, since they reset the sinus node, but atrial or supraventricular bigeminy can occur. If the PACs are very premature, the wavefront can encounter a refractory AV node and not be conducted. This can be mistaken for sinus bradycardia if the PAC is buried in the T wave since the PAC will reset the SA node and lead to a long P–P interval. Diagnosis
Rule of bigeminy
When the atrial rhythm is irregular (as in atrial fibrillation or sinus arrythmia) the presence of bigeminy depends on the length of the P–P interval and happens more frequently with a longer interval. As with post PVC pauses, a longer P–P interval leads to a higher chance of re-entrant circuits and thus PVCs. The term "rule of bigeminy" is used to refer to the dependence of bigeminy on the ventricular cycle length in irregular rhythms. Classification
There can be similar patterns depending on the frequency of abnormal beats. If every other beat is abnormal, it is described as bigeminal. If every third beat is aberrant, it is trigeminal; every fourth would be quadrigeminal. Typically, if every fifth or more beat is abnormal, the aberrant beat would be termed occasional.Bigeminy is contrasted with couplets, which are paired abnormal beats.
