Matching a pulse description to its heart trace
- biology

- 14-16
Students read how a patient's pulse feels and pick the matching heart trace from four drawn on standard squared paper. The options are pictures, not words, so the question tests reading a trace rather than recalling a name.
Sample question
A **58-year-old** patient is connected to a heart monitor. A nurse records the pulse as **regular and very fast, about 180 beats per minute; the patient feels faint**. <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 360 150" width="360" height="150" role="img" aria-label="One heartbeat on squared paper"><title>One normal heartbeat</title><g stroke="currentColor" stroke-opacity="0.18" stroke-width="1" fill="none"><line x1="20" y1="10" x2="20" y2="130"/><line x1="40" y1="10" x2="40" y2="130"/><line x1="60" y1="10" x2="60" y2="130"/><line x1="80" y1="10" x2="80" y2="130"/><line x1="100" y1="10" x2="100" y2="130"/><line x1="120" y1="10" x2="120" y2="130"/><line x1="140" y1="10" x2="140" y2="130"/><line x1="160" y1="10" x2="160" y2="130"/><line x1="180" y1="10" x2="180" y2="130"/><line x1="200" y1="10" x2="200" y2="130"/><line x1="220" y1="10" x2="220" y2="130"/><line x1="240" y1="10" x2="240" y2="130"/><line x1="260" y1="10" x2="260" y2="130"/><line x1="280" y1="10" x2="280" y2="130"/><line x1="300" y1="10" x2="300" y2="130"/><line x1="320" y1="10" x2="320" y2="130"/><line x1="340" y1="10" x2="340" y2="130"/><line x1="360" y1="10" x2="360" y2="130"/><line x1="20" y1="10" x2="340" y2="10"/><line x1="20" y1="30" x2="340" y2="30"/><line x1="20" y1="50" x2="340" y2="50"/><line x1="20" y1="70" x2="340" y2="70"/><line x1="20" y1="90" x2="340" y2="90"/><line x1="20" y1="110" x2="340" y2="110"/><line x1="20" y1="130" x2="340" y2="130"/></g><rect x="20" y="10" width="100" height="100" fill="none" stroke="currentColor" stroke-opacity="0.55" stroke-width="1.5"/><path fill="none" stroke="currentColor" stroke-width="2.5" stroke-linejoin="round" d="M20 90 L70 90 Q85 76 100 90 L130 90 L138 96 L146 30 L154 104 L162 90 L196 90 Q214 64 232 90 L340 90"/><text x="85" y="70" font-size="12" fill="currentColor" text-anchor="middle">P</text><text x="150" y="24" font-size="12" fill="currentColor" text-anchor="middle">QRS</text><text x="214" y="60" font-size="12" fill="currentColor" text-anchor="middle">T</text><text x="70" y="126" font-size="11" fill="currentColor" text-anchor="middle">one large square = 0.2 s</text></svg> Which trace matches that description?
