 Item No. SCP-3349 Object Class Keter Special Containment Procedures Individuals affected by SCP-3349 are to be admitted indefinitely as inpatients under routine care and Foundation long-term acute care facilities, so as not to re-expose SCP-3349 to civilian physicians and the medical community at large. Inclusive instances are to be intercepted by field agents, who are to use experiential discretion regarding the use of Class-A amnestics. The cardiac activity of patients admitted with SCP-3349 is to be monitored at all times by a centralized telemetry unit, continuously staffed with two 12-hour shift clerical personnel. Instances of SCP-3349 are to be reported by the clerical staff to the nursing staff promptly via an exclusive telephone line. Individual manifestations of SCP-3349 are to be captured when possible. The print-outs catalog both in the patient's analog and electronic record. Beginning in 1941, SCP-3349 has been actively expunged from the civilian medical community and literature, initially per endeavors of Mobile Task Force Gamma 5, Red Herons, and since continued by the ongoing global acquisition and obscuration of case studies by the DEA. Description SCP-3349 is a non-fatal cardiac arrhythmia that has a 42.8% incidence following a specific sequence of intravenous drug administrations. 150mg IV drip of amiodarone infused over 15 minutes. One gram IV infusion of magnesium infused over 1 hour. One ampule of sodium bicarbonate infused over 3-4 minutes. 0.1mg IV of epinephrine, immediate push. SCP-3349 is not constant and appears periodically in the affected individual with an average of 9 occurrences per day, lasting for an average of 3 minutes per occurrence. Objectively, SCP-3349 produces a fluttering central and peripheral pulse upon palpation, often described as tactically similar to a purr of phyllus catus, the common house cat, and can be auscultated with a stethoscope. The clinical descriptions also cited in the purr of phyllus catus. Charleston M.E. Pompeo, B. Alessa, K.L. and Mackenzie D.W., 1972. SCP-3349, a multi-center longitudinal cohort study, 1942. Foundation Quarterly Journal of Medicine, 45 in parentheses, 233-253. On electrocardiogram, SCP-3349's manifestations display commonalities with the waveforms of human vocalizations. Spectrographically reconstructed audio signals based on SCP-3349's electrical signatures produce various intonations of human-like laughter, whaling, and speech. See audio data below. Approximated via analysis and resynthesis sound spectrograph. Auditory outputs resembling the purr of phyllus catus has also been reported. SCP-3349 is non-curable and is refractory to defibrillation at 200, 300, and 360 joules. There are no known precipitating or alleviating factors regarding SCP-3349, other than the aforementioned induction. Despite the erratic electrical activity, patients remain stable, though few may experience some reduction in exercise tolerance. Audio Data A classic presentation of SCP-3349.

Janice ██████ Medical record number ██████ April 28, 1996, 1651 Patient supine, resting comfortably in no acute distress. No events overnight. Identified are a man speaking Arabic and an attempt at a telephone conversation. Michael ██████ Medical record number ██████ January 10, 1960, 1334 Patient sitting and conversing normally, discussing current events. A male voice is identified. Clerical transcriptions and voice recognition software have interpreted the input as possibly being one of the following phrases. Help me. Hell believe. Hell. Please. Help. Please. Richard ██████ Medical record number ██████ January 10, 1961, 1334 Patient sleeping during time of capture. A female voice is identified saying the following phrase. Firefighters, emergency personnel responding to toxic spills, researchers, more specialists cleaning up contaminated facilities with breathing apparatus. The phrase is found in now defunct Foundation protocols, current at the time of recording, regarding hazardous occupational spills. Addenda ██████ Addendum ██████, 3349.01 In 1957, then Chief of Cardiology Dr. Robert Wohk II tested the conversational ability of SCP-3349 under the assumption it was sentient. Below is a surviving transcript of the test. Transcription. Type provided by Certified Stenographer appointed by the Foundation. June 6, 1957, 827 West Wing Room 439. Subject, Macy ██████ Present are Dr. Robert Wohk, Dr. W, Kathy Williams Registered Nurse, C, Beverly McIntosh Registered Nurse, B, Susan Bolero, Typist. Patient is lying supine in 4-point restraints. EKG leads attached. Dr. W, Bev, can we get in the, uh, B? The amulet is pulled. Just going to put it in the saline, Dr. W. Okay, good. B, what are you going to say, Dr. W? Dr. W, don't know, Bev. C, EKG is ready. Dr. W, let's begin. This is Macy ██████, 32-year-old white BML, past medical history of hysteria and celiac disease. No known drug allergies or surgical history. The medications indicated in the procedure notes are prepared and we are accessing by a left external juggler's central catheter. Medical number is ██████, all in agreement? All, yes. 836. Dr. Wohk's SSW induces the arrhythmia. Dr. W, alright, can we pull the machine over closer? I can't see it. C, is that it? There? Dr. W. I don't know, Kathy, I need to see. Alright, keep the blood pressure cuff cycling. 837. Dr. Wohk and his staff initiate messages. Hello, greetings. What is your name? Coded and Morrison delivered by one, playing the auditory sequence near the ear of the patient. Two, manual percussion of the sternum. And three, electrical impulses via transvenous pacing. The doctor places his stethoscope on the patient's chest. Dr. W, can you hear me? Dr. Moose has stepped the scope to various points. Registered nurses continue repeating the messages and Morse code. Dr. W, we would like to speak with you if that is alright. You can trust me. Can you tell me who you are? Do you have a name? EKG and machine beeping, no change. The rhythm is evident and pronounced. No response from the patient or the team. Dr. W, I say this is a doctor. I am attempting to speak with you. If you can hear me, then let us know somehow. No indication of a reply. The doctor takes his stethoscope off after several minutes of searching and listening. Dr. W, this is as ridiculous as a seance. Turn all that ██████ off. Registered nurses comply and the test is aborted. Addendum 3349.02 Over 60 years after the above session, junior researcher Mark Regimer, since promoted, recovered the actual EKG printouts, previously presumed lost, and submitted them the novel methods to approximate the captured signatures of spectrograms. Below are the outputs when set to logarithmic scales. Spectrogram 3349.dw.01 Spectrogram 3349.dw.02 Cross-reference with Foundation data suggests with a 95% confidence interval that the youth depicted in the above spectrograms defeated the deceased daughter of Dr. Wode, who was lost to a pedestrian versus automobile collision at the untimely age of 6. Additional attempts at communication with SCP-3349 are currently being authorized.
