Giving Beta Blockers to Someone with Mobitz Ii Heart Block
Introduction At the conclusion of this case study, the learner will be able to:
Identify two common treatment modalities for Second degree heart block
Identify a list of uses of, doses and contraindications for giving Beta Blockers.
Recognise a Mobitz II heart block rhythm.
Over the path of the paper, a definition of Mobitz II heart block will be given a long with what can happen to the rhythm if beta blocker medications are taken at the same time and its treatment.
The intensive care unit involved is 12 beds in a private hospital that predominately does heart surgery including coronary artery bypass grafts, valve replacements and repairs, craniotomies and some high dependency beds.
All research articles on both Mobitz II heart block and Metoprolol advise that people shouldn’t be given beta blockers if they are have any block further than first degree heart block. S.G. Webb (personal communication, September 17, 2009) notes that there is not many studies and journal articles done with regards to giving Metoprolol to patients in Mobitz II heart block as it should not be happening. Mr Webb is an Intensivist in two leading Perth hospitals and stated that he can recall three incidences where a beta blocker was given to a heart block patient causing complete heart block.
Introduction to topic
Mr Cecil Jones, a 74-year-old male, was admitted to the intensive care unit for the purpose of a coronary angiogram, echocardiogram and possible cardiac bypass. Five days previously, Cecil had presented to an emergency department with complaints of shortness of breath on exertion, pneunoperiteum (PNO) and orthopnea. After being treated at the previous hospital for acute pulmonary odema (APO), secondary to a Non-Stemi with a Troponin level of 0.88l/min and was treated accordingly with Frusemide and continuous positive airway pressure (CPAP).
He has no previous history of cardiac arrhythmias but he does have a history of hypertension, hypercholesterolemia and
