We present an interesting case of a young male whose main manifestation of Lyme carditis was isolated LBBB. He also had mild Lyme myocarditis. The patient was successfully treated with oral doxycycline, and his isolated LBBB and myocarditis rapidly resolved.

Discussion Bradycardia is a heart rate below what the lowest value that is normal for age. Infants and children have higher heart rates that slowly decrease with age to adult levels. It is usually noted as an incidental finding because of increased vagal tone. Reasons for cardiology referral include associated heart murmur, syncope especially if associated with exercise or unusual triggers, other signs such as chest pain or palpitations, family history of sudden cardiac death, congenital heart disease or familial heart disease, bradycardic medication use, or unusual symptoms associated with the concern. Severe bradycardia ...

Written by Pendell Meyers(with really great and thorough explanation of this finding by Ken Grauer).At my hospital, patients with any symptoms which could be vaguely interpreted as a possible stroke during the triage process are brought to the high acuity area and a provider is asked to do a " neuro check " , which involves a quick H and P and exam to determine if we should activate our stroke protocol.A man in his 70s was brought to me for a neuro check, and the triage providers commented that they were worried about a possible seizure as well. The patient was alert and oriented with normal vitals at triage. He ...

This was sent by a Saleh Hatem, an avid reader of the blog.The patient presented with chest pain:There is a narrow complex tachycardia.Is there inferior ST Elevation?Here was my interpretation:What appears to be ST Elevation in inferior leads is really a P-wave that is contiguous with the QRS. (The next bump over is a T-wave that looks like a P-wave!).Since the P-wave is not inverted, it is NOT retrograde, and therefore it is a native sinus beat.  This sinus beat does conduct, but there is severely prolonged PR interval (severe first degree AV block), with a PR interval of over 400 ms.So: Sinus tachycardia with severe...

We report the case of a 67-year-old man with a consumptive syndrome with two subpleural pulmonary opacities. A transthoracic lung biopsy revealed a Dirofilaria worm. Myocardial nuclear magnetic resonance (NMR) demonstrated dilated cardiomyopathy after myocarditis related to dirofilariasis. Human infection is rare and occurs accidentally. The most common radiological alteration is a mainly subpleural coin lesion. Dirofilariasis is a neglected emergent disease and knowledge about it is important for differential diagnoses from neoplastic pulmonary nodules.

We describe the case of fulminant myocarditis due to Lyme disease and use of mechanical circulatory support (MCS) for the treatment of the Lyme carditis associated with refractory cardiogenic shock. Fulminant Lyme myocarditis in young adult male patient led to a sudden onset of acute, severe biventricular heart failure with progressive cardiogenic shock, and multiorgan failure immediately after admission.
