Hydroxychloroquine and azithromycin or Zithromax, currently being tested as both prophylaxis and therapy for CoVid19 infections, work together to induce dangerous electrocardiographic changes.  This the conclusion of NYU cardiac electrophysiologists studying 84 CoVid19 patients treated at their hospital.


After 3-4 days of therapy with this drug cocktail, 11% of CoVid19 patients developed a prolonged QT interval of greater than 500 milliseconds.  This EKG change is associated with sudden cardiac death due to severe arrhythmias.


These drugs may turn out to be lifesaving but they are not for do-it-yourselfers.  Their use requires careful and repeated cardiac monitoring.  Using hydroxychloroquin and Zithromax yourself may prevent CoVid19 but only because you die first.
