We describe a case of ventricular pacemaker spikes delivered on the T wave causing PMVT.Case:A 53-year-old female with CAD s/p stent, postpartum cardiomyopathy s/p Bi-V CRT-D (Boston Scientific G124), and paroxysmal atrial fibrillation presented for elective endoscopy and colonoscopy to evaluate her dysphagia and abdominal pain.

The patient is female in her 80s with a medical hx of previous MI with PCI and stent placement. She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. She also has a hx of paroxysmal atrial fibrillation and is on oral anticoagulant treatment. small squares in width (260ms).

She was taken to the cath lab, where she was found to have 100% in-stent restenosis of the proximal LAD. A temporary pacemaker was implanted, and she was admitted to the ICU with cardiogenic shock. About 45 minutes after the second EKG, the patient was found in cardiac arrest. She was worked as a full code, and ROSC was achieved.

And finally, after placement of a stent in the LAD: Before and after: (Unfortunately, this resulted in the "jailing" of the septal branches behind the stent and probably some degree of plaque shift which is why they do not opacify well in the "after" shot. This was the cost of preventing infarction of the anterior wall.)

He had previously undergone non‐contrasted head computed tomography (NCHCT) (magnetic resonance imaging (MRI) was unable to be performed secondary to pacemaker), which did not reveal strokes. Episodes always occurred after activity and only upon sitting. His initial computed tomography angiogram (CTA) of the head and neck was unremarkable.

Edits by Meyers and Smith A man in his 70s with PMH of hypertension, hyperlipidemia, type 2 diabetes, CVA, dual-chamber Medtronic pacemaker, presented to the ED for evaluation of acute chest pain. So the patient was taken for emergent cath, showing: Culprit artery: LAD (100% stenosis, TIMI 0) requiring thrombectomy and stent.

The patient was then taken to the cath lab an found to have a proximal RCA 100% thrombotic occlusion which was successfully stented. The transvenous pacemaker was removed the following day and pressors were not required again. Peak troponin T was 3.00 ng/mL (highly elevated). Post-cath ECG with resolution of acute changes.

He was rushed to the Cath Lab where an LAD culprit lesion was stented. Here is the LAD after stent placement. I initially suspected V2 as being placed too high on the chest, but there is no accompanying inverted P wave here, so the positioning is sound. It’s important to stress the presence of a normal QRS (i.e.,

Also a h/o LV aneurysm with thrombus, on anticoagulation, as well as a dual chamber pacemaker. It was opened and stented with resulting TIMI-3 (normal) flow. The stent to LCX is patent. She had a history of PCI to the circumflex and also of severe mitral regurgitation, status post bioprosthetic valve replacement.

Slow TIMI 2 initially with brisk flow status post percutaneous coronary intervention with 18mm drug-eluting stent. It is also not a wandering pacemaker — because change in atrial pacing site is gradual with that disorder. In the available view, the RCA appears fully occluded. To our knowledge, the patient did well.

Some patients with pacemakers and metal prosthesis can’t be exposed to such strong magnetic fields. It is a super specialised discipline. It requires very expensive machinery. It is inherently uncomfortable for the patient as you have to lie in a tight tunnel for up to an hour.

So in heart failure, one procedure that can help improve quality of life is the implantation of a biventricular pacemaker. It is worth knowing that people who may not have been deemed suitable for heart transplantation once upon a time may now be candidates because the laws around organ donation have changed.

These issues can only be addressed in an ICCU (Intensive Coronary Care Unit) setting, where temporary pacemakers and defibrillators are available. Then angioplasty is performed, and a medical device called a stent (metallic scaffold) is deployed in the artery to open the blood flow. This is known as a pharmaco-invasive approach.
