Compare conditions

Put any two — or three — conditions side by side, adult or pediatric, to spot the look-alike differences fast, row by row.

Falls and Syncope
—
In one line
  • ·When older people fall or pass out, something upstream is broken—find it and fix it before the next fall breaks a bone or the next faint stops the heart for good.
—
Normal physiology
  • ·Staying upright and conscious requires three systems working as one team: the heart pumps five liters of blood every minute and adjusts its speed to match demand, the autonomic nervous system (the body's autopilot) squeezes blood vessels to keep pressure steady when you stand, and the balance system—eyes, inner-ear sensors, joint sensors, and the cerebellum (the brain's balance computer in the back)—keeps you stable and walking straight.

What goes wrong
  • ·A fall or fainting (syncope) happens when one or more of those three systems fails. The heart might pump too little blood because it beats too slow (heart block), too fast and chaotically (atrial fibrillation, ventricular a fast heart rate (tachycardia)), or because a valve is so stiff or leaky that forward flow drops. Blood pressure might crash when you stand (orthostatic low blood pressure (hypotension)) because you are dehydrated, your medicines (especially blood-pressure pills, diuretics, or sedatives) pushed it too low, or your autonomic nerves are damaged by diabetes or aging and cannot squeeze vessels fast enough. Your brain might lose blood flow suddenly in a mini-stroke (TIA) or misfire in a seizure, leaving you confused or unconscious. The inner ear might send spinning signals (vertigo) from crystals that broke loose (BPPV) or inflammation (labyrinthitis), making you lose balance. Muscles might be too weak from disuse or sarcopenia (age-related muscle loss), vision too blurry from cataracts, or reflexes too slow from sedating medicines like benzodiazepines or opioids. Often it is not one cause but a pile-up: a patient on three blood-pressure medicines who skips breakfast, stands up fast, and has worn-out autonomic nerves will faint; an older adult on a sedative with weak legs and poor vision will trip and fall.

Hallmark signs
  • ·Sudden loss of consciousness (passing out completely)
  • ·Feeling dizzy or lightheaded right before falling
  • ·No memory of the fall itself
  • ·Pale or sweaty skin just before or during the episode
  • ·Quick recovery (back to normal within a minute or two)
  • ·Confusion or slow thinking for several minutes after waking up
  • ·Chest pain or pounding heart before or after the fall
  • ·New trouble speaking, weakness on one side, or vision loss after the fall
—
Red flags · escalate now
  • ·Chest pain, shortness of breath, or a racing heart before or after the fall
  • ·Confusion, slurred speech, weakness on one side, or vision loss that does not go away quickly
  • ·Fall happened during exercise or while lying down (suggests a heart rhythm problem, not just low blood pressure)
  • ·Family history of sudden death before age 50 (raises concern for inherited heart rhythm disorders)
  • ·Very slow heart rate (under 40 beats per minute) or very fast rate (over 150) on exam or monitor
—
Workup
  • ·Electrocardiogram (ECG or EKG) — 12-lead tracing of heart electricity
  • ·Orthostatic vital signs — blood pressure and pulse lying, sitting, and standing at 1 and 3 minutes
  • ·Complete blood count (CBC) — measures red cells, white cells, and platelets
  • ·Basic metabolic panel (BMP) — sodium, potassium, glucose, kidney function (creatinine)
  • ·Troponin (heart muscle damage marker)
  • ·Brain natriuretic peptide (BNP or NT-proBNP)
  • ·Continuous heart monitor (telemetry in hospital or outpatient Holter or event monitor)
  • ·Echocardiogram (ultrasound of the heart)
—
Treatment
  • ·Stop or reduce blood pressure medicines, diuretics (water pills), and sedatives
  • ·Increase salt and water intake — aim 2 to 3 liters of fluid daily and add salt to meals (if no heart failure)
  • ·Compression stockings (waist-high, 30–40 mmHg) and abdominal binder
  • ·Fludrocortisone (Florinef) 0.1–0.2 mg daily — a steroid that tells kidneys to hold salt and water
  • ·Midodrine (ProAmatine) 2.5–10 mg three times daily — squeezes blood vessels to raise pressure
  • ·Pacemaker implant for slow heart rate (bradycardia < 40 bpm) or heart block
  • ·Medicine or ablation for fast arrhythmias — beta-blockers, calcium-channel blockers, or catheter burning of bad rhythm spots
—
NCLEX trap
  • ·A fall or fainting spell is a red flag that something deeper is broken — the heart's rhythm, blood pressure control, medicine overload, or a brain problem. Your job is to find and fix that root cause, not just hand out a walking aid and hope for the best.
  • ·Fainting (Syncope) means the person passes out suddenly and wakes up fast — usually within seconds — because blood stopped reaching the brain. If they woke up quickly with no memory of convulsing, suspect a heart or blood-pressure problem first. Start with orthostatic vital signs (blood pressure lying down, then standing), a continuous heart monitor (telemetry or Holter), and an echocardiogram (ultrasound of the heart). Save the EEG for cases where the history points to a seizure: jerking movements, tongue-biting, confusion lasting many minutes after waking, or loss of bladder control.
  • ·Polypharmacy — too many medicines — is one of the top causes of falls and fainting (syncope), especially in older adults. If blood pressure is dropping too low (especially when standing), you need to work with the team to deprescribe: stop or reduce the drugs that are no longer needed. Then recheck orthostatic vitals. Fixing medicine overload often solves the problem.
  • ·Falls and fainting (syncope) are never normal at any age. Every episode has a cause: an arrhythmia (irregular heartbeat), orthostatic low blood pressure (hypotension) (blood pressure drops when standing), a medication side effect, dehydration, a stroke, or another condition. Find the cause and treat it, or the person is at high risk for a serious injury (like a hip fracture) or sudden death.
  • ·Start with the basics: orthostatic vital signs, a 12-lead ECG, continuous cardiac monitoring, and an echocardiogram. Only order brain imaging (CT or MRI) if the history or neuro exam suggests a stroke, bleed, seizure, or structural brain problem — for example, new focal weakness, severe headache, altered mental status that doesn't clear, or a witnessed convulsion. Don't scan every fall.
  • ·A fall or syncopal episode means the underlying problem is still there and will likely cause another event. Discharging someone home alone without fixing the root cause sets them up for a repeat fall — this time with a broken hip, head bleed, or sudden cardiac death. Ensure the cause is identified, treated, and that the patient has support and safety measures in place before discharge.
