Timoptic (timinol) Induced Bradycardia?

Image
A 60 year old patient with a history of glaucoma, hypertension, and CHF.  The home meds were Betoptic (dorzolamide) BID, Timoptic (timinol) BID,  Cozaar (losartan)  qd, ASA qd, and Lasix (furosemide) BID.   The patient was admitted to the hospital with bradycardia, dizziness, and presyncopal episodes.  The cardiac enzymes were WNL.  An echo showed that the CHF was stable with a normal EF.  The cardiologist suggested that the bradycardia might be a side effect of the Timoptic (Timinol) eye drops.   The monitor shows some extreme bradycardia with AV dissociation. After 48 hours after cessation of the Timoptic the rhythm remained unchanged and a diagnosis of sick sinus syndrome was made On the 4th day, the patient received an implanted pacemaker

Pacemaker Problems

Image
This strips shows an AV paced rhythm.   After the 4th complex there is failure to capture.  The fifth complex show failure to sense.  The AV interval on the sixth complex is shorter than the previous paced beats.  Between the 7th and 8th complex there is failure to capture.  The 8th complex is a fusion complex.

Serum potassium > 7.0  mEq/L is associated with conduction abnormalities and bradycardia: Prolonged QRS interval with bizarre QRS morphology High-grade AV block with slow junctional and ventricular escape rhythms Any kind of conduction block (bundle branch blocks, fascicular blocks) Sinus bradycardia or slow AF Development of a sine wave appearance (a pre-terminal rhythm) From Life in the Fast Lane https://lifeinthefastlane.com/ecg-library/basics/hyperkalaemia/
