46yo female presented with palpitation, no medical history. No p wave? Junctional paroxysmal tachycardia?

Similar cases

bottom strip: HR 70s, SR 1 degree AVB; top strip: HR 120s, rhythm unsure of. Looking for possible interpretations. Junctional tachy has been suggested, however the QRS is fairly wide (but does not have a BBB), and it looks to me like the p wave is buried between the QRS and the T wave. What do you all think?

81 y/o F c/o palpitations, hemodynamically stable

For the prior case I posted - in the ED he was given adenosine to disrupt his "AVRNT" and this was the strip.

A 52-year-old man presented with a 20-minute history of chest pain radiating to the left shoulder and neck, associated with dyspnea and diaphoresis. He had a history of hypertension, long-term smoking, and a sedentary lifestyle. On physical examination, bibasilar crackles were noted on lung auscultation. An electrocardiogram (ECG) was performed in the primary care setting, and the patient was promptly referred to the emergency department.

A 28-year-old woman presented with a 3-day history of intense pruritus over the lower back. She reported no recent travel or exposure to new environments. She cares for a small kennel with approximately eight dogs rescued from the streets. Physical examination revealed multiple small vesicles, some clustered and others scattered, predominantly involving the lumbar region and the left gluteal area.

A 4-month-old male infant presented with skin lesions localized to the chin for the past 3 days. Physical examination revealed multiple small pustules with surrounding inflammatory signs on the chin, along with a few scattered papules on the chest.

patient in late teens presenting after a collapse, no chest pain, no previous cardiac history, no history of sudden death in family, are there any features in this ekg that would warrant further work-up or is this just a pediatric ekg?
